You guys should try some version of Carbotanium. Pagani used that in one of their cars about 7 or 8 years ago. I've made Armor bits out of Carbon Fiber mixed with powdered Metals, Ceramic, and Graphite. I've made Armor bits from Fiber Glass as well. I've made some Layered Armor bits from Carbon Fiber, Fiber Glass, Abilone Shell Fiber (made the same way as Carbon Fiber and Fiber Glass), Ceramic with Graphite mixed in, then both sides covered in Salt Soaked Denim (3 Day soak just like the Aztecs), then both of those get a nice Leather (more for looks and comfort than practical) Stands up to bullets pretty good. 4 inches thick is a bit much, but it's a quarter the weight of Modern Class 3 Body Armor.
Carbon Fiber, developed by Alliant Technologies. Created to replace steel and aluminum while creating a lowered radar reflection. Sadly the crap available to civilians does none of that as the resins needed to create Armor level Carbon Fiber are not currently available in any quantity. Not to mention that the true Carbon Chain Fiber, made from fly ash from IPP and woven by HEXCEL is not available to civilians either.
@@user-qx3lm4vw6eis it not available because it's impossible to produce without a military budget and isn't being sold to civilians? Is it regulated strictly?
@@sakesaurus Actually yes, it's availability has to be approved by DARPA and DHS. But there are decent knockoffs available from China that would be more than adequate for LARP. Hoyt Easton is one of the few civilian companies currently using the HEXCEL produced fiber for their ACC arrow shafts. But the Chinese knockoffs work comparably well but lack the longevity.
@@dankdaze42069Even before I was born the economy of the US was made to keep people poor and companys rich and if Trump gets president again, it will get worse, since he owns a big company and will do all he could to make himself more rich. I know no other industrial country, where you have to work 2-3 low wage full time jobs just to stay alive without going into dept. In fact in my country you could live off a part-time minimum wage job.
The thing about carbon fiber is that it's nearly weightless, 2 layers would barely add encumberance, but over a gambeson would appear to be highly effective.
Carbon fiber is several times the strength of steel per mass, but it is also very brittle. When its breaking force is reached it fails abruptly. You need to laminate it with a strong, flexible material like Kevlar, Dyneema, or Spectra, and you need a minimum of 10 layers (probably more) if you intend to stop arrows from a war bow. Also, the epoxy must be vacuum chambered and cured in a kiln or oven to remove air bubbles and catalyze the resin to maximum strength. The resin manufacturer can tell you the optimum temperature to cure at but if memory serves it is somewhere in the neighborhood of 80 to 90 deg. C (aerospace standards) to achieve maximum strength.
@@davidbeppler3032It might embed still. Give it an even harder top layer to deflect. In case of "Then what's the point of the carbon fiber". To be a solid backbone and prevent the deflection surface from deforming or caving into a dent that can lead to penetration. The resin could catch the tip of an arrow and stop it from deflecting. But a pure surface has a better chance of letting it slide off
When I was younger, I was on my high school rowing team and one day we got a criminal, fiber shell, and you are indeed correct it’s a miraculous material but it’s very brittle It is very vulnerable to crush forces. Bumps that thing on the dock one day, just a little bit and just opened gaping hole. So carbon, fiber armor would be great at all kinds of cutting attacks and someone, but you bring a mace to it or an ax and it’s gonna go right through.
They cannot, as the state they are in (Victoria) has prohibited body armour Control of Weapons Regulations 2021 bans the use and ownership of body armour by the public.
@@AlyssMa7rin The government: Only we're allowed to have guns. Also the government: You're also not allowed to wear armour against the only people that have guns.
When will people realise that the people in the government have absolutely no care for you? the only way you become a politician is to become a backstabbing snake with no morals.
@@HvacHeathenNot really. I've seen what a properly shaped iron breast plate can take, and it's a hell of a lot more than a small brick can. I don't even know if shaping carbon fiber in the same way would yield comparable results until I see it done tbh. A big part of me doubts it because carbon fiber just isn't like other materials. The strength comes from the weave and not necessarily the shape of the object it's made into.
@@PoopFactor4 Another thing is that different materials have different resistances to different types of trauma. Steel is amazingly good when it comes to taking pressure, which makes it an amazing material when it comes to armour. Carbon fiber isn't, it shines when it comes to resistance against expanding. That's why it's amazing material for space projects and was a terrible material for a submarine. So it would be hard to shape carbon fiber in such a way that it would truly shine when it comes to resistance to external forces.
Carbon fibre on it's own is not an effective armour. It's light and rigid, not tough. Carbon fibre sandwiching a layer of kevlar, repeated 16 times however. Now you are getting some fairly cut resistant armour at least.
The durability seemed fairly good for such thin sheets. You could easily make armor multiple sheets thick and still be lighter or thinner than regular armor. Something multiple sheets thick would probably be quite good.
I'm not convinced of that at all. Not from what I just saw. I'd have to see a properly shaped piece of armour made from carbon fiber get shot to make that kind of claim. I've seen what mild steel can do to stop arrows when properly shaped and treated. I.e. it can stop a 160 lbs longbow and take almost no damage. That carbon fiber struggled with 110 lbs and the arrow still got through. The problem with carbon fiber is that the moment it takes damage, it becomes so much weaker for the next blow.
@@himedo1512 Carbon fiber is about 1/3 to 1/4 the density of steel. It makes a good amount of difference, but it's not exactly a super futuristic ultramaterial. 4mm thick carbon fiber plate armor would be awesome, be able to stop 12th century cannons, and be the same weight as plate armor of the day, but having armor that's that thick would cause problems around points of articulation. Not to mention that the knight would be very unlikely to survive the cannon, regardless of blunt penetration. The biggest issue with carbon fiber is how inflexible and fragile it is when you're using resin. Against a war pick, hardened steel would likely perform as well as or even better than carbon fiber that has been properly meshed and hardened simply because most steels deform so well and are less likely to shatter into multiple pieces. In alot of ways, it's similar in effectiveness to ceramic armor. Super effective against a single shot, but after that, it rapidly becomes extremely useless.
@@BWeManX Unless you're expecting half a dozen disposable squires to follow you around on the battlefield, replacing broken plates, it's not terribly useful after the first few hits. The benefit of carbon fiber is that it can be weaved into a very lightweight and nigh-unbreakable soft material in order to replace chainmail. Plate armor only makes sense if you're able to R&D a diamond hard composite material that won't fall apart when shattered.
If you're comparing modern materials maybe check for polycarbonate sheets like Lexan. These are used for replacing windows in areas at risk of vandalism as, while they may scratch, they're resistant to breaking and, too a limited extent, small arms. Quarter inch thick is standard but it would be easy enough to cut a sheet and bolt several layers together. It might actually work better than carbon fiber for armor or shields as it's softer and less likely to shatter.
I believe you need a much thicker layer of lexan to withstand the same amount of punishment as carbon fiber, so it's definitely less efficient, but I guess it would be more cost-effective. I have worked with lexan and steel sheets before and from my experience, a 1.5 mm thick lexan was easier to cut than a 0.5 mm thick mild steel and a 8 mm thick lexan was easier to saw through than a 1 mm thick mild steel (with the appropriate saws). But I have obviously not tried arrows or bullets (or carbon fiber). Speaking of bullets, Scott from Kentucky Ballistics easily blasted through a half inch thick "bulletproof" lexan with a standard 9 mm pistol. So you gotta get extra thick with those to start stopping some bullets.
@@Sukenus polycarbonate is NOT hard. It's not resistant to scratching, sawing, miling, and similar types of damage. What i noticed tho, is that it doesn't crack or shatter from blunt force, it bends like metal instead, to an extent. I had lexan industrial-grade protective googles that wore of and weren't usable anymore, so i shot them with a pellet gun. They stopped the pellet, but it left a dent similar to ones that are left in sheet metal, sleek round shaped, with no signs of cracking that you'd expect from plastic. I think the googles were like 1.5mm thick polycarbonate.
@@Sukenus Polycarbonate itself isn't bulletproof and anyone that believes it is, is an idiot. It is however, one of two materials used in bullet resistant glass. Glass fragments the bullet. Polycarbonate absorbs the fragments. It is worth mentioning that transparent aluminum does a much better job, being capable of stopping .50 bmg in the same thickness as the typical layering for ballistic glass is made for stopping normal rifle rounds.
even when the piercing strikes got through, the CF did a good job of stopping them before they really got to a lethal level. If you had padding beneath, it would be even better
CF is a great ingredient for composite armor. Important part is composite. There's a new technique to make graphene. It's really cheap, but a lot of time consuming lab manual labor. For a one-off suit of armor it would probably be worth it, I would throw some of that in the resin. I would also add a few layers of Kevlar so it's useful in a modern context as well. I would also continue to use metal plates but make them half the thickness and back them with the composites. So you end up with the same weight but double the protection or same protection and half the weight.
Be careful with frayed carbon fiber. The little ends are sharp and can work into your skin. The splinters wont directly cause an infection either as carbon is a natural part of the body, and can work in deep and cause damage.
Those are the same reasons it was considred, and then rejected, for use in implants (like hip replacements) The body won't react to it, sure. But if its ever damaged/starts decaying, it would cause major problems.
I'm imagining putting this over textile armor would be a really good combo. Giving it something to diffuse the force into. Probably still wouldn't be as durable as plate, but might be pretty darn good, especially vs any kind of cutting slashing action. Seems like its only really weak against piercing stuff, but if it stops it enough that it wouldn't get through the textile underneath, might nonetheless still be really effective.
It could be highly effective spaces armour. Bind an outer carapace with one about half an inch under by the edges. Run bolts and nuts through as support pillars, the ends can be smooth on the outer shell if desired. Otherwise it may wear your opponent more to have their strikes unpredictably stopped in jarring fashion. Of course under that, still the other stuff
It seems it pierced fairly easily, but got rapidly slowed down. I think the fibers got pushed apart, which meant they tried to squish back together, causing friction on the arrow. Steel and the like are more likely to bend out of the way.
@@MrRourk It will be worse. Broadheads are made to slice through unarmored flesh of game animals or burglars. The field point on the first shot was the best tip they could have used of the ones they had. A bodkin would have been superior to all others. The second head they used was a semi-broadhead and the fiber stopped it almost outright. The one you listed, while beautiful and functional, would fare worse. The fiber would catch the blades and just outright stop it. This is what gambesons are for; the weave catches wider arrow blades and can even hamper bodkins.
I work in composites as my day job and I can tell you there is not really much of a point of using foam core in a carbon fiber sword. The sword is going to be thin enough as it is that you won't need many layers of carbon fiber to make a traditionaly thick sword. I would just make sure you have at least one layer of UD in the center of the sword to give it rigidity. Biaxe UD Biaxe would probably do the trick. For weight balance I would just put something more dense than carbon fiber in the hilt. Definetly do a vaccum bag after you layup. Infustion would be prefered but thats more complex, you can just wet layup and throw it in a vacum bag and apply like a bar and a half of pressure to it and there yah go.
Skeletonized steel core was my thought. For balance you could do a bit of tungsten or something in the hilt. Depending on the total weight, of course. I think the steel cire is important to holding an edge against other weapons. Skeletonized for weight, and would probably have benefits in structure. Then the carbon fiber maybe inset on the sides if possible to add the remaining rigidity. I think this would work especially well in the blade of Ichigo from Bleach. The curved design would allow for plenty of deflection and glide. To me that means even if you manage to be overwhelmed with a giant sword, it should be light enough and tough enough to not let you down. Hopefully resulting in a genuinely useful partner if for some reason you have to use a sword
So for the curious I made a Kevlar piece and kept a UV damaged piece for the guys which will arrive in their hands soon. No core, just 7 layers or so of biax and a basket weave in the middle most layer. The goal not being to make armour as such, to do that we just go thick, rather we just are trying combinations of materials to see how little mass and size is required to achieve the results. Also, for any questions you have about the carbon sword, ask away and I’ll do my best to answer below.
Nice work here! Modern combat armor combines kevlar with plates of ceramics like silicon carbide. Have you ever done any experiments in this direction?
@@jamesyoungquist6923 yes, with plates of metal, 3d printed materials, carbon fibre, cast ceramic and tile. Resin impregnated kevlar wrapped around those items helps to contain them when fractured, and soft densely woven kevlar works as a shock damper behind that fracture surface which breaks up projectiles. For a shield, I'm thinking a light foam core, with Carbon Fibre and Kevlar layers front and back would be incredibly light and hold up to a surprising amount of punishment.
What you guys need to do now is test a sheet of steal that is twice as thick as the big square. While it would be a shot video, it would work as a "Base Line" so everyone can see how useful carbon fiber is.
For the sake of a fair comparison, you'd want the same thickness for all the test samples. I think comparing aluminum to carbon fiber would also be an interesting test.
@@kaylinosprey3306 I only suggested double because I'm fairly positive a strong sharp might puncture .5mm steel sheet. Oddly enough a google search failed to even consider this. I don't know about you, but google as a search engine is getting worse and worse.
I am a retired aircraft technician and have a lot of experience with advanced composites. Carbon fiber is very strong but it is not very resistant to cutting or being pierced. Kevlar is far more resistant to being cut and pierced. All of the modern body armor uses a lot of kevlar. Most bullet resistant vests for higher caliber bullets also use ceramic and steel plates. I think for resistance to swords and arrows several layers of kevlar with a backing of carbon fiber would work well. Also if you have access to plate armor you should use it as a form. Put on several coats of mold release wax then do a wet layup starting with 3 or 4 layers of carbon fiber (the first sheet should have the weave being at zero degrees in relation to top and bottom of the breast plate with the 2nd layer being oriented at 45 degrees with the 3rd layer 45 degrees opposite to the 2nd layer with the 4th layer at 90 degrees. Then follow up with several layers of kevlar with the same orientations as the previous ones. Then put this into a vacuum bag with a vacuum pump while the resin cures. Look up how to vacuum bag a composite layup. Before putting it in the vacuum bag you put a sheet of perforated plastic sheet, then a sheet of breather cloth. The perforated sheet is usually mylar that has a series of small holes on a 3/8th inch pattern and the breather cloth is very similar to polyester fiber fill sheets used in making quilts. This is readily available at fabric stores, the thicker the better. The perforated sheet prevents the breather sheet from sticking to the layup. The holes in the perforated allows the excess resin to be sucked out, the breather sheet serves two purposes. It absorpts the excess resin as well as giving the vacuum bag to evenly apply the force of the bag across the whole part. When you suck the air out the air that surrounds the part presses down with 14.6 lbs per square inch. Using a vacuum bag gives an optimized ratio of resin to cloth which gives the most strength. A resin rich lay up is far weaker and very brittle. You will find that a composite breast plate with its compound curves will be very strong and should resist sword blows as well as arrows. If arrows pierce it make one with more layers of kevlar.
@@MissionSilo Now you mention it that is true and the last thing I recall reading was to do with the suspected health hazards they pose to respiratory system. I do remember (perhaps incorrectly) testing indicated significant improvement in flex and strength... It also feels we are one step away from suggesting Mytheril in terms of absurdity 😁
@@justinhollis5579I mean. Most strong fibers can ruin your lungs. Fiber glass. Carbon fiber. Carbon nano tubes. It's important to wear the proper ppe. Speaking from experience, bad lungs REALLY suck
Even though I'm not TOO big on the whole "competition" side, you gotta love Tyranth's understanding of materials and making/building. And you gotta love Nate's YEARS of experience on wielding and using weapons. Together, they were the ideal hosts for this test.
The arrow was very impressive. A mil of steel and Boromir would have been absolutely skewered. Considering the width and weight I think it did great. I think a mil of sheet steel on the outer layer would go a long way to stopping the edges and a thicker middle layer of foam would go a long way to stopping and absorbing a lot more kinetic force to slow down the chops and cuts before they transfer all that force through the entire piece on a very thin point or edge. And it wouldn't add much ofma difference in weight.
Evidently James is pretty passionate about the sword project if he volunteered samples for testing as armor. I hope he’s pleased with the results which honestly surprised me as well. It’s not as good as steel but is far better than say wood, the classical organic composite shields are made of.
One problem I want to bring to attention is that non of these pieces look shaped like armor would be to redirect and deflect the energy of blows, for example arrows or axe blows would have a harder time connecting a perpendicular hit and glance off on shaped armor. If using flatter pieces, having stacks laced together more akin to traditional Samurai armor would have been a better test if wanting to use simple flat pieces.
Carbon Fiber doesn't respond well to direct impact and penetration - the material is simply too brittle by nature. My advice is trying out the 'CFRP-Stainless Steel Superbeam' concept, which is fairly new in construction and architecture. The way it works is by 'Jacketing' each material in order to increase the structural integrity. It's basically a carbon-fiber core coated in resin, encased in steel. If you intend on making the Titan Sword, it should at least cut down on the frame's weight while offering up to 95% more load strength. That means you can use almost half the intended weight to support the frame, and still get the same sword.
I'm no material scientist of any kind but would fiber based materials be weaker against piercing forces like stabs and arrows than solid materials due to the fibers separating?
I make carbon fiber aerospace parts. Some of the window pieces they cut out will absolutely stop everything you have there and most modern arms. Thickness matters.
While carbon fiber on it's own is very strong, it does not have a particularly high abrasion resistance. When making anti penetration panels like those found on race cars for nearly this exact same reason, you normally rely on Aramid fibers such as Kevlar or Zylon. If you add a core structure in order to add stiffness while keeping weight down you are practically relying on the strength of the foam rather than the strength of the fibers and resin. The bonds in the structure of the foam will fail before the Carbon, and then it will buckle as there is no structure supporting it anymore and you will see it separate like the example you showed. It was not de-laminated, the core failed. Cheers, Love the videos.
I believe fiberglass would make a better armor. One of the main properties of carbon fiber is its stiffness, but in armor you need to dissipitate force. Making the armor from fiberglass would allow it to flex when hit and then return to its original shape, which should allow it to perform better. I imagine an ideal armor would be fiberglass with a thin sheet of stainless steel or titanium over the surface.
That's good for most things. Bad for piercing. If something can make a dent and still has energy left it will pierce. Plus fiber glass has safety issues aside from that, meaning if your armour is damaged and you live, your wound will itch, your respiratory system will be affected. It's a whole thing. Polycarbonate though is excellent for impact resistance with none of those issues.
@@hf117j While true, fiberglass is also very strong. This means properly shaped fiberglass armor will deflect piercing blows before they cause the material to flex. It's only when the blade bites in that all of the energy will be transferred in and potentially pierce the armor. This is one of the reasons I suggested plating a thin layer of a high hardness metal over the surface, as this will help prevent weapon tips from biting in. As for the itchy wounds, the resin will hold the fibers in place, so it's not likely to be an issue. Regardless, I'd rather have an itchy wound than a pole arm through my chest.
You could make a sick shield out of carbon fiber (with a steel rim). It would be way less cumbersome and more protective than your usual wooden shield. You could even pad the front of the carbon fiber shield to reduce incoming blows even more
When carbon fiber is under tension, it holds up well. Under compression it tends to delaminate and crush. The edged weapons pierced pretty well, and the axe and katana would snap the resin, causing the whole plate to collapse. One important point about these, same as Kevlar for vests, is that they take damage from each hit and do become more likely to fail with every hit. If an officer takes fire and their vest is hit, that vest is expended and needs to be replaced.
I have been wondering about carbon fiber for armor. It feels like it could be a good stand in for some type of mythical metal but I never knew it it would actually be that useful against medieval weapons.
Carbon Fiber is weak to penetrative force. Using composite fabrics may provide better results. There are Carbon/Kevlar, Carbon/Fiberglass, and Carbon/Innegra available, so each layer has both fabrics. *As a thought, finding which type/grouping of the above composites performed best, then laminating them onto the Wyrmwick polyurethane armor Shad previously tested may be an amazing armor.
I saw your video yesterday on the state of the channel. I have really strong anecdotal evidence to contribute. I'm working on a composite material project. A number of times I've searched terms related to "carbon fiber" on YT over the passed month. I've been steering towards boring lecture and fabrication type stuff and more towards exotic materials but this was popular, released recently, a channel I've spent dozens of hours on, and very very topical. This should have ABSOLUTELY been recommended to me. It's also a great alternative to all the powerpoint presentations.
Good video, although you should try a heavy vacuum pressed 50 layer carbon fiber 1cm thick plate... Expensive? Yes, but it is used on the Beechcraft premier belly, so it can take some hits and some serious punishment...
I have no idea how expensive it would be, but I'd love to see some testing of laser-sintered printed steel armor--say, with a hexagonal structure to allow it to be thicker and more resistant for the same or less weight. Also, shouldn't these sample tests be secured against a gambeson backing?
The loose fit actually helps the carbon fiber here as the force is allowed to tilt the piece inward and increase the final angle at which the force of the edges are at their greatest.
If you want to stop an arrow with carbon fiber, then you need to have a ceramic backing or a tight multiple link chain mail. Something else that might work is a small honeycomb aluminum core 1/8" thick. 10 layers total sandwiching the aluminum honeycomb core, but the 1st layers should be unidirectional up and down. 2nd is a 45 directional left to right, 3rd unidirectional left to right, 4th 45 directional right to left, 5th 90 tight weave, then 1/8" thick aluminum honey comb core repeat the back layers as front.
It's funny that you've done this, we were just down at the archery range firing arrows at carbon fibre and fibreglass pieces to see how they'd do (spoilers, not well). Got another more extensive test planned with different layers, cloth weights, as well as some kevlar parts.
It's a bit worrying that the swords bite into the edge of the fibers so easily, as those are the dimensions you'd really want to keep their shape if they were swung against something else (though I guess they're omitting the hard steel edges and possible springy materials to cushion the blow). I love how the different parts of the axe were used against the actually-tough carbon fibres so we got an idea of how well they actually work (especially after hearing so many people swear axes/picks weren't "really" used against it.)
It would be interesting but maybe steel over carbon fiber might be stronger. The steel has a little bend to it that could cushion the shock of the rigid carbon fiber plate.
Carbon fiber is strongest under tension. That’s why they were layered in that manner. When you strike face on you induce tension. When you strike edge on you induce compression. For CF; Tension = good, compression = bad.
From what I've always understood. Carbon Fiber will only stop blunt force trauma, Like a bullet, but even then an armor piercing bullet will go right through. This is a very entertaining channel.
What you have to understand about carbon fibre is that it has an incredibly high stiffness to mass ratio. Meaning it can withstand an awful lot of stress without deflecting, with minimal amount of material. It is however wuite brittle, meaning it shatters relatively easily with any concentrated impact force. This is why carbon fibre is used for high performance vehocles such as F1 cars and airplanes. Composite materials such as kevlar are the opposite, kevlar is able to absorb a great deal of impact force but deflects a lot under load. This is why kevlar is great for body armour, it can absorb the impact of a bullet without shearing, but you wouldn't want your car chassis made out of it because it would bend every time you went round a tight corner. And it is much heavier in comparison. Then fibreglass is a decent middle ground for most general purpose uses such as canoes and kayaks.
I'd love to see a cartoon make something call an American Woad Ninja, the warrior would have the Arkansas Toothpick, Tomahawk with a backspike, woad colored smoke grenades that also disperses chaff, the english warbow, the ninjas throwing spikes, and the active camouflage from gits only calling it, "The Ghillie Dhu Camo."
A double layer of the fibre that's spaced might hold up better. By the time the broadest portion seems to sink into the structure, the slower moving edge won't have enough momentum to get through the second layer.
This is the sword tuber equivilent of the gun tuber armor plate debate. Ceramics? Or steel plates?. Unfortunately carbon fiber isnt great at shock absorbtion. Ceramic plates (of which there are several types including those not actually ceramic) have a limit until they crack ir shatter in which case theyre useless. While steel can be hit numerous times....but is a shit load heavier.
from what i'm seeing.. the best combination might be a mixt between carbon fiber plates and some very light cloth armor. because the cloth will be able to stop even more of the thrust the arrows are dealing. for example you pack carbon fiber in some cloth armor and place them in pockets.. you'll definetly be able to stop arrows cuts and thrusts ( but may not stop the one with the spike that punctured the carbon earlier ) forgot to add, even the pockets would stop some of the force because it's in a pocket and if the armor is kinda moveable ( meaning if the arrow hits the armor itself will disperse the pressure as well like a t shirt being pulled on to the side while wearing it or something)
I think that with carbon fiber being low mass/density, as well as having planes or vectors of weakness, it necessitates being used in a multi material, multi layer composite when the aim is to create something truly strong or durable. For instance, if you wanted a functional cuirass: You might use steel rod to make a wireframe form, use chicken wire as a base for layers of epoxied fiberglass, polypropylene, and your carbon fiber. If cost is no object, you might mix carbon nanotubes into the epoxy/polypropylene to create a more structural lattice, thereby increasing the rigidity in soft layers and durability of brittle ones.
If using it for armor I am pretty sure you could make it a lot thicker and still be lighter than steel. I'm sure most people know this already, but how the layers are laid out matters. Just like how I've seen people making bullet proof plates out of fiberglass and epoxy, orienting each layer at an angle to the previous layer made it stronger.
there's a company who makes camera equipment and accessories for camera rigs called smallrig, they make 15mm carbon fiber rods at varying lengths. if you were looking for something to chop, those type of rods are probably reasonably priced to do testing on
The delamination issue could probably be solved cheaply by drilling a few holes and putting pop rivets in strategic places. One could also vastly increase it's armor value without increasing the weight to much by using cheap metal strapping with holes to run a mesh across the armor, makes it much stronger vs bladed weapons but doesn't do much for arrows, the attachment points then serves the same purpose as the pop rivets.
the foam would act as a frangable layer to absorb shock, but once it cracks, it's not providing protection; in the same way as motorcycle helmets do. aka, you get one hit in any area before protection is significantly lost. There'd need a different solution, esp since sowrds and shock go together
The thing with carbon fiber is that it’s strong *per-unit-weight*. So really, to compare apples-to-apples vs an equivalent steel product, you’d have to give the carbon fiber enough layers/thickness to give it an equivalent weight to the steel. This is more fair. So, start thick on the carbon fiber, then dial it back to the point where you are realizing the weight savings again, but still stronger than the steel.
You would back a metal sleeve or armor with carbon fiber. The metal has a higher hardness making cutting into it harder, the CF is stronger and prevents the metal from caving or breaking on strikes, especially if the CF is more flexible. Maybe D30, or similar reactive material, for shock absorption.
I would go with a sort of steep V shape of metal over top of the carbon fiber for the blade otherwise the carbon fiber around the blade will get worn away when you hit things with it.
Something I remember from when I was a kid was a character who’s used a sword and its metal scabbard as an off hand parrying weapon, how practical would that be?

Sadly the crap available to civilians does none of that as the resins needed to create Armor level Carbon Fiber are not currently available in any quantity. Not to mention that the true Carbon Chain Fiber, made from fly ash from IPP and woven by HEXCEL is not available to civilians either.
@@user-qx3lm4vw6eis it not available because it's impossible to produce without a military budget and isn't being sold to civilians? Is it regulated strictly?
@@sakesaurus Actually yes, it's availability has to be approved by DARPA and DHS. But there are decent knockoffs available from China that would be more than adequate for LARP.
Hoyt Easton is one of the few civilian companies currently using the HEXCEL produced fiber for their ACC arrow shafts. But the Chinese knockoffs work comparably well but lack the longevity.

The thing about carbon fiber is that it's nearly weightless, 2 layers would barely add encumberance, but over a gambeson would appear to be highly effective.
armadillo style rounded plate lamellar over gambeson would be dope
Especially if the gambeson had some Kevlar on it.

You going to hell 🔥😂😂😂
Carbon fiber is several times the strength of steel per mass, but it is also very brittle. When its breaking force is reached it fails abruptly. You need to laminate it with a strong, flexible material like Kevlar, Dyneema, or Spectra, and you need a minimum of 10 layers (probably more) if you intend to stop arrows from a war bow. Also, the epoxy must be vacuum chambered and cured in a kiln or oven to remove air bubbles and catalyze the resin to maximum strength. The resin manufacturer can tell you the optimum temperature to cure at but if memory serves it is somewhere in the neighborhood of 80 to 90 deg. C (aerospace standards) to achieve maximum strength.
Yep, it would be an inch thick if it was the same weight as steel. Doubt an arrow will penetrate an inch of carbon fiber.
@@davidbeppler3032It might embed still. Give it an even harder top layer to deflect. In case of "Then what's the point of the carbon fiber". To be a solid backbone and prevent the deflection surface from deforming or caving into a dent that can lead to penetration. The resin could catch the tip of an arrow and stop it from deflecting. But a pure surface has a better chance of letting it slide off
When I was younger, I was on my high school rowing team and one day we got a criminal, fiber shell, and you are indeed correct it’s a miraculous material but it’s very brittle It is very vulnerable to crush forces. Bumps that thing on the dock one day, just a little bit and just opened gaping hole. So carbon, fiber armor would be great at all kinds of cutting attacks and someone, but you bring a mace to it or an ax and it’s gonna go right through.

“We got penetration”, says Tyranth…
I wonder how resistant shaped Carbon-fiber is towards swords…
These small bricks aren’t telling much.
Would a small brick of plated iron not provide some information?
@@HvacHeathenNot really. I've seen what a properly shaped iron breast plate can take, and it's a hell of a lot more than a small brick can. I don't even know if shaping carbon fiber in the same way would yield comparable results until I see it done tbh. A big part of me doubts it because carbon fiber just isn't like other materials. The strength comes from the weave and not necessarily the shape of the object it's made into.
@@PoopFactor4 Another thing is that different materials have different resistances to different types of trauma. Steel is amazingly good when it comes to taking pressure, which makes it an amazing material when it comes to armour. Carbon fiber isn't, it shines when it comes to resistance against expanding. That's why it's amazing material for space projects and was a terrible material for a submarine.
So it would be hard to shape carbon fiber in such a way that it would truly shine when it comes to resistance to external forces.
Carbon fibre on it's own is not an effective armour. It's light and rigid, not tough.
Carbon fibre sandwiching a layer of kevlar, repeated 16 times however. Now you are getting some fairly cut resistant armour at least.
Make the Carbon Fiber an inch thick and show me an arrow going through it. ;)
AHHHH I CAN'T WAIT FOR THE TITAN SWORD. SUPPORT THEM AT ALL COSTSSS
The durability seemed fairly good for such thin sheets. You could easily make armor multiple sheets thick and still be lighter or thinner than regular armor. Something multiple sheets thick would probably be quite good.
I'm not convinced of that at all. Not from what I just saw. I'd have to see a properly shaped piece of armour made from carbon fiber get shot to make that kind of claim. I've seen what mild steel can do to stop arrows when properly shaped and treated. I.e. it can stop a 160 lbs longbow and take almost no damage. That carbon fiber struggled with 110 lbs and the arrow still got through. The problem with carbon fiber is that the moment it takes damage, it becomes so much weaker for the next blow.
@@PoopFactor4and was the steel as light as the carbon fiber was in these tests?
@@himedo1512 Carbon fiber is about 1/3 to 1/4 the density of steel. It makes a good amount of difference, but it's not exactly a super futuristic ultramaterial. 4mm thick carbon fiber plate armor would be awesome, be able to stop 12th century cannons, and be the same weight as plate armor of the day, but having armor that's that thick would cause problems around points of articulation. Not to mention that the knight would be very unlikely to survive the cannon, regardless of blunt penetration. The biggest issue with carbon fiber is how inflexible and fragile it is when you're using resin. Against a war pick, hardened steel would likely perform as well as or even better than carbon fiber that has been properly meshed and hardened simply because most steels deform so well and are less likely to shatter into multiple pieces.
In alot of ways, it's similar in effectiveness to ceramic armor. Super effective against a single shot, but after that, it rapidly becomes extremely useless.
@@commode7x carbon fiber plate carriers for days
@@BWeManX Unless you're expecting half a dozen disposable squires to follow you around on the battlefield, replacing broken plates, it's not terribly useful after the first few hits. The benefit of carbon fiber is that it can be weaved into a very lightweight and nigh-unbreakable soft material in order to replace chainmail. Plate armor only makes sense if you're able to R&D a diamond hard composite material that won't fall apart when shattered.
I heard a story about a man that went insane.
He bought a new boomerang and kept trying to throw the old one away.
If you're comparing modern materials maybe check for polycarbonate sheets like Lexan. These are used for replacing windows in areas at risk of vandalism as, while they may scratch, they're resistant to breaking and, too a limited extent, small arms. Quarter inch thick is standard but it would be easy enough to cut a sheet and bolt several layers together. It might actually work better than carbon fiber for armor or shields as it's softer and less likely to shatter.
I believe you need a much thicker layer of lexan to withstand the same amount of punishment as carbon fiber, so it's definitely less efficient, but I guess it would be more cost-effective.
I have worked with lexan and steel sheets before and from my experience, a 1.5 mm thick lexan was easier to cut than a 0.5 mm thick mild steel and a 8 mm thick lexan was easier to saw through than a 1 mm thick mild steel (with the appropriate saws). But I have obviously not tried arrows or bullets (or carbon fiber).
Speaking of bullets, Scott from Kentucky Ballistics easily blasted through a half inch thick "bulletproof" lexan with a standard 9 mm pistol. So you gotta get extra thick with those to start stopping some bullets.
Then composite for all purpose armor?
Honestly HDPE would probably be even more interesting in this application.
@@Sukenus polycarbonate is NOT hard. It's not resistant to scratching, sawing, miling, and similar types of damage. What i noticed tho, is that it doesn't crack or shatter from blunt force, it bends like metal instead, to an extent. I had lexan industrial-grade protective googles that wore of and weren't usable anymore, so i shot them with a pellet gun. They stopped the pellet, but it left a dent similar to ones that are left in sheet metal, sleek round shaped, with no signs of cracking that you'd expect from plastic. I think the googles were like 1.5mm thick polycarbonate.
@@Sukenus Polycarbonate itself isn't bulletproof and anyone that believes it is, is an idiot. It is however, one of two materials used in bullet resistant glass. Glass fragments the bullet. Polycarbonate absorbs the fragments. It is worth mentioning that transparent aluminum does a much better job, being capable of stopping .50 bmg in the same thickness as the typical layering for ballistic glass is made for stopping normal rifle rounds.

@@AliothAncalagon that's a very good point.

Important part is composite.
There's a new technique to make graphene. It's really cheap, but a lot of time consuming lab manual labor. For a one-off suit of armor it would probably be worth it, I would throw some of that in the resin.
I would also add a few layers of Kevlar so it's useful in a modern context as well.
I would also continue to use metal plates but make them half the thickness and back them with the composites.
So you end up with the same weight but double the protection or same protection and half the weight.

Be careful with frayed carbon fiber. The little ends are sharp and can work into your skin. The splinters wont directly cause an infection either as carbon is a natural part of the body, and can work in deep and cause damage.

Those are the same reasons it was considred, and then rejected, for use in implants (like hip replacements)
The body won't react to it, sure. But if its ever damaged/starts decaying, it would cause major problems.
I'm imagining putting this over textile armor would be a really good combo. Giving it something to diffuse the force into. Probably still wouldn't be as durable as plate, but might be pretty darn good, especially vs any kind of cutting slashing action. Seems like its only really weak against piercing stuff, but if it stops it enough that it wouldn't get through the textile underneath, might nonetheless still be really effective.
It could be highly effective spaces armour. Bind an outer carapace with one about half an inch under by the edges. Run bolts and nuts through as support pillars, the ends can be smooth on the outer shell if desired. Otherwise it may wear your opponent more to have their strikes unpredictably stopped in jarring fashion. Of course under that, still the other stuff
the arrow test suprised me. considering it was a very thin piece and flat + the arrow did get stuck pretty early.
It seems it pierced fairly easily, but got rapidly slowed down. I think the fibers got pushed apart, which meant they tried to squish back together, causing friction on the arrow. Steel and the like are more likely to bend out of the way.
They need to try that again with Tusker Broadheads
@@MrRourk It will be worse. Broadheads are made to slice through unarmored flesh of game animals or burglars. The field point on the first shot was the best tip they could have used of the ones they had. A bodkin would have been superior to all others. The second head they used was a semi-broadhead and the fiber stopped it almost outright. The one you listed, while beautiful and functional, would fare worse. The fiber would catch the blades and just outright stop it. This is what gambesons are for; the weave catches wider arrow blades and can even hamper bodkins.

I work in composites as my day job and I can tell you there is not really much of a point of using foam core in a carbon fiber sword. The sword is going to be thin enough as it is that you won't need many layers of carbon fiber to make a traditionaly thick sword. I would just make sure you have at least one layer of UD in the center of the sword to give it rigidity. Biaxe UD Biaxe would probably do the trick. For weight balance I would just put something more dense than carbon fiber in the hilt. Definetly do a vaccum bag after you layup. Infustion would be prefered but thats more complex, you can just wet layup and throw it in a vacum bag and apply like a bar and a half of pressure to it and there yah go.
Skeletonized steel core was my thought. For balance you could do a bit of tungsten or something in the hilt. Depending on the total weight, of course. I think the steel cire is important to holding an edge against other weapons. Skeletonized for weight, and would probably have benefits in structure. Then the carbon fiber maybe inset on the sides if possible to add the remaining rigidity. I think this would work especially well in the blade of Ichigo from Bleach. The curved design would allow for plenty of deflection and glide. To me that means even if you manage to be overwhelmed with a giant sword, it should be light enough and tough enough to not let you down. Hopefully resulting in a genuinely useful partner if for some reason you have to use a sword
We're lucky Boromir doesn't have real eyes, his two-thousand yards stare would be crushing.
time to become a patreon. so we can actually see a full body armor with exchangeable parts.
They can't make body armour because Australia's government is trash.
So for the curious I made a Kevlar piece and kept a UV damaged piece for the guys which will arrive in their hands soon. No core, just 7 layers or so of biax and a basket weave in the middle most layer. The goal not being to make armour as such, to do that we just go thick, rather we just are trying combinations of materials to see how little mass and size is required to achieve the results.
Also, for any questions you have about the carbon sword, ask away and I’ll do my best to answer below.
Nice work here! Modern combat armor combines kevlar with plates of ceramics like silicon carbide. Have you ever done any experiments in this direction?
@@jamesyoungquist6923 yes, with plates of metal, 3d printed materials, carbon fibre, cast ceramic and tile. Resin impregnated kevlar wrapped around those items helps to contain them when fractured, and soft densely woven kevlar works as a shock damper behind that fracture surface which breaks up projectiles. For a shield, I'm thinking a light foam core, with Carbon Fibre and Kevlar layers front and back would be incredibly light and hold up to a surprising amount of punishment.
@@jamesmckenzie9551 dude that's awesome. Can't wait to see the results
What you guys need to do now is test a sheet of steal that is twice as thick as the big square. While it would be a shot video, it would work as a "Base Line" so everyone can see how useful carbon fiber is.
For the sake of a fair comparison, you'd want the same thickness for all the test samples. I think comparing aluminum to carbon fiber would also be an interesting test.
@@kaylinosprey3306 I only suggested double because I'm fairly positive a strong sharp might puncture .5mm steel sheet. Oddly enough a google search failed to even consider this.
I don't know about you, but google as a search engine is getting worse and worse.
In general carbon fiber is more comparable to aluminum. So I agree with the other person
I am a retired aircraft technician and have a lot of experience with advanced composites. Carbon fiber is very strong but it is not very resistant to cutting or being pierced. Kevlar is far more resistant to being cut and pierced. All of the modern body armor uses a lot of kevlar. Most bullet resistant vests for higher caliber bullets also use ceramic and steel plates. I think for resistance to swords and arrows several layers of kevlar with a backing of carbon fiber would work well. Also if you have access to plate armor you should use it as a form. Put on several coats of mold release wax then do a wet layup starting with 3 or 4 layers of carbon fiber (the first sheet should have the weave being at zero degrees in relation to top and bottom of the breast plate with the 2nd layer being oriented at 45 degrees with the 3rd layer 45 degrees opposite to the 2nd layer with the 4th layer at 90 degrees. Then follow up with several layers of kevlar with the same orientations as the previous ones. Then put this into a vacuum bag with a vacuum pump while the resin cures. Look up how to vacuum bag a composite layup. Before putting it in the vacuum bag you put a sheet of perforated plastic sheet, then a sheet of breather cloth. The perforated sheet is usually mylar that has a series of small holes on a 3/8th inch pattern and the breather cloth is very similar to polyester fiber fill sheets used in making quilts. This is readily available at fabric stores, the thicker the better. The perforated sheet prevents the breather sheet from sticking to the layup. The holes in the perforated allows the excess resin to be sucked out, the breather sheet serves two purposes. It absorpts the excess resin as well as giving the vacuum bag to evenly apply the force of the bag across the whole part. When you suck the air out the air that surrounds the part presses down with 14.6 lbs per square inch. Using a vacuum bag gives an optimized ratio of resin to cloth which gives the most strength. A resin rich lay up is far weaker and very brittle. You will find that a composite breast plate with its compound curves will be very strong and should resist sword blows as well as arrows. If arrows pierce it make one with more layers of kevlar.

The arrow was very impressive. A mil of steel and Boromir would have been absolutely skewered. Considering the width and weight I think it did great. I think a mil of sheet steel on the outer layer would go a long way to stopping the edges and a thicker middle layer of foam would go a long way to stopping and absorbing a lot more kinetic force to slow down the chops and cuts before they transfer all that force through the entire piece on a very thin point or edge. And it wouldn't add much ofma difference in weight.
Yes! I've been saying this for like months! Old armor : New materials! Thank you!
Today I learnt that Nate watches CGPgrey and has learnt the truth about hexagons
Evidently James is pretty passionate about the sword project if he volunteered samples for testing as armor. I hope he’s pleased with the results which honestly surprised me as well. It’s not as good as steel but is far better than say wood, the classical organic composite shields are made of.
Time to test pure-resin armor.
get one of those larper plastic armors?..
I've got you, we'll just get the guys to paint shad with resin and voila.
One problem I want to bring to attention is that non of these pieces look shaped like armor would be to redirect and deflect the energy of blows, for example arrows or axe blows would have a harder time connecting a perpendicular hit and glance off on shaped armor. If using flatter pieces, having stacks laced together more akin to traditional Samurai armor would have been a better test if wanting to use simple flat pieces.
such a underated channel, I love their content 😊
Carbon Fiber doesn't respond well to direct impact and penetration - the material is simply too brittle by nature. My advice is trying out the 'CFRP-Stainless Steel Superbeam' concept, which is fairly new in construction and architecture. The way it works is by 'Jacketing' each material in order to increase the structural integrity. It's basically a carbon-fiber core coated in resin, encased in steel. If you intend on making the Titan Sword, it should at least cut down on the frame's weight while offering up to 95% more load strength. That means you can use almost half the intended weight to support the frame, and still get the same sword.
You tested padding, mail, tyres, plate and carbon fiber........ But what about Dragons?

Just wanted to say Shad, youve lost a noticeable amount of weight and you look good man! Proud of you!
I'm no material scientist of any kind but would fiber based materials be weaker against piercing forces like stabs and arrows than solid materials due to the fibers separating?
I make carbon fiber aerospace parts. Some of the window pieces they cut out will absolutely stop everything you have there and most modern arms. Thickness matters.
While carbon fiber on it's own is very strong, it does not have a particularly high abrasion resistance. When making anti penetration panels like those found on race cars for nearly this exact same reason, you normally rely on Aramid fibers such as Kevlar or Zylon.
If you add a core structure in order to add stiffness while keeping weight down you are practically relying on the strength of the foam rather than the strength of the fibers and resin. The bonds in the structure of the foam will fail before the Carbon, and then it will buckle as there is no structure supporting it anymore and you will see it separate like the example you showed. It was not de-laminated, the core failed.
Cheers,
Love the videos.
Couple this with steel wire tire armor 😅
I believe fiberglass would make a better armor. One of the main properties of carbon fiber is its stiffness, but in armor you need to dissipitate force. Making the armor from fiberglass would allow it to flex when hit and then return to its original shape, which should allow it to perform better. I imagine an ideal armor would be fiberglass with a thin sheet of stainless steel or titanium over the surface.
That's good for most things. Bad for piercing. If something can make a dent and still has energy left it will pierce. Plus fiber glass has safety issues aside from that, meaning if your armour is damaged and you live, your wound will itch, your respiratory system will be affected. It's a whole thing. Polycarbonate though is excellent for impact resistance with none of those issues.
@@hf117j While true, fiberglass is also very strong. This means properly shaped fiberglass armor will deflect piercing blows before they cause the material to flex.
It's only when the blade bites in that all of the energy will be transferred in and potentially pierce the armor. This is one of the reasons I suggested plating a thin layer of a high hardness metal over the surface, as this will help prevent weapon tips from biting in.
As for the itchy wounds, the resin will hold the fibers in place, so it's not likely to be an issue. Regardless, I'd rather have an itchy wound than a pole arm through my chest.

Great interaction guys - love your back and forth jibing at each other. Nice tests

When carbon fiber is under tension, it holds up well. Under compression it tends to delaminate and crush. The edged weapons pierced pretty well, and the axe and katana would snap the resin, causing the whole plate to collapse. One important point about these, same as Kevlar for vests, is that they take damage from each hit and do become more likely to fail with every hit. If an officer takes fire and their vest is hit, that vest is expended and needs to be replaced.

Thanks for the video, the bromance is real lol
Carbon fiber did much better than I expected in regards to cutting. Overall it went as expected. Nice to see I was proven wrong. 😄
Carbon Fiber is weak to penetrative force. Using composite fabrics may provide better results.
There are Carbon/Kevlar, Carbon/Fiberglass, and Carbon/Innegra available, so each layer has both fabrics.
*As a thought, finding which type/grouping of the above composites performed best, then laminating them onto the Wyrmwick polyurethane armor Shad previously tested may be an amazing armor.
I saw your video yesterday on the state of the channel. I have really strong anecdotal evidence to contribute. I'm working on a composite material project. A number of times I've searched terms related to "carbon fiber" on YT over the passed month. I've been steering towards boring lecture and fabrication type stuff and more towards exotic materials but this was popular, released recently, a channel I've spent dozens of hours on, and very very topical. This should have ABSOLUTELY been recommended to me. It's also a great alternative to all the powerpoint presentations.
Good video, although you should try a heavy vacuum pressed 50 layer carbon fiber 1cm thick plate... Expensive? Yes, but it is used on the Beechcraft premier belly, so it can take some hits and some serious punishment...
I have no idea how expensive it would be, but I'd love to see some testing of laser-sintered printed steel armor--say, with a hexagonal structure to allow it to be thicker and more resistant for the same or less weight. Also, shouldn't these sample tests be secured against a gambeson backing?
They really should have. Everything that was tested on the dummy tended to bounce around even on a solid strike.
The loose fit actually helps the carbon fiber here as the force is allowed to tilt the piece inward and increase the final angle at which the force of the edges are at their greatest.
If you want to stop an arrow with carbon fiber, then you need to have a ceramic backing or a tight multiple link chain mail. Something else that might work is a small honeycomb aluminum core 1/8" thick. 10 layers total sandwiching the aluminum honeycomb core, but the 1st layers should be unidirectional up and down. 2nd is a 45 directional left to right, 3rd unidirectional left to right, 4th 45 directional right to left, 5th 90 tight weave, then 1/8" thick aluminum honey comb core repeat the back layers as front.
Be interesting to make a carbon fiber breastplate with an outer chainmail layer and test it vs a traditional metal breastplate of the same weight.
It's funny that you've done this, we were just down at the archery range firing arrows at carbon fibre and fibreglass pieces to see how they'd do (spoilers, not well). Got another more extensive test planned with different layers, cloth weights, as well as some kevlar parts.
It's a bit worrying that the swords bite into the edge of the fibers so easily, as those are the dimensions you'd really want to keep their shape if they were swung against something else (though I guess they're omitting the hard steel edges and possible springy materials to cushion the blow).
I love how the different parts of the axe were used against the actually-tough carbon fibres so we got an idea of how well they actually work (especially after hearing so many people swear axes/picks weren't "really" used against it.)
I think that steel armor with carbon fibre layered on top should be tested. 🤔
It would be interesting but maybe steel over carbon fiber might be stronger. The steel has a little bend to it that could cushion the shock of the rigid carbon fiber plate.
Considering those carbon fiber pieces are practically as thin as paper and unfinished, the fact they could stand up at all to any hit is amazing.
Entertaining video. Good job, guys.
Carbon fiber is strongest under tension. That’s why they were layered in that manner. When you strike face on you induce tension. When you strike edge on you induce compression. For CF; Tension = good, compression = bad.
Would have been cool to have a sheet of steel in equivalent thickness to test against.
or steel with equivalent mass.
From what I've always understood. Carbon Fiber will only stop blunt force trauma, Like a bullet, but even then an armor piercing bullet will go right through. This is a very entertaining channel.
What you have to understand about carbon fibre is that it has an incredibly high stiffness to mass ratio. Meaning it can withstand an awful lot of stress without deflecting, with minimal amount of material. It is however wuite brittle, meaning it shatters relatively easily with any concentrated impact force. This is why carbon fibre is used for high performance vehocles such as F1 cars and airplanes.
Composite materials such as kevlar are the opposite, kevlar is able to absorb a great deal of impact force but deflects a lot under load. This is why kevlar is great for body armour, it can absorb the impact of a bullet without shearing, but you wouldn't want your car chassis made out of it because it would bend every time you went round a tight corner. And it is much heavier in comparison.
Then fibreglass is a decent middle ground for most general purpose uses such as canoes and kayaks.
I'd love to see a cartoon make something call an American Woad Ninja, the warrior would have the Arkansas Toothpick, Tomahawk with a backspike, woad colored smoke grenades that also disperses chaff, the english warbow, the ninjas throwing spikes, and the active camouflage from gits only calling it, "The Ghillie Dhu Camo."
A double layer of the fibre that's spaced might hold up better. By the time the broadest portion seems to sink into the structure, the slower moving edge won't have enough momentum to get through the second layer.
This is the sword tuber equivilent of the gun tuber armor plate debate. Ceramics? Or steel plates?.
Unfortunately carbon fiber isnt great at shock absorbtion.
Ceramic plates (of which there are several types including those not actually ceramic) have a limit until they crack ir shatter in which case theyre useless. While steel can be hit numerous times....but is a shit load heavier.
from what i'm seeing.. the best combination might be a mixt between carbon fiber plates and some very light cloth armor. because the cloth will be able to stop even more of the thrust the arrows are dealing. for example you pack carbon fiber in some cloth armor and place them in pockets.. you'll definetly be able to stop arrows cuts and thrusts ( but may not stop the one with the spike that punctured the carbon earlier )
forgot to add, even the pockets would stop some of the force because it's in a pocket and if the armor is kinda moveable ( meaning if the arrow hits the armor itself will disperse the pressure as well like a t shirt being pulled on to the side while wearing it or something)
ty really does have quite a bit of strength.
I think trying to add a layer of aluminum would add a lot to the carbon fiber because aluminum is very sticky when trying to be cut.
Hey Shad, love your channel and especially how you're turning it into a business. Keep on your path!
I think that with carbon fiber being low mass/density, as well as having planes or vectors of weakness, it necessitates being used in a multi material, multi layer composite when the aim is to create something truly strong or durable.
For instance, if you wanted a functional cuirass: You might use steel rod to make a wireframe form, use chicken wire as a base for layers of epoxied fiberglass, polypropylene, and your carbon fiber. If cost is no object, you might mix carbon nanotubes into the epoxy/polypropylene to create a more structural lattice, thereby increasing the rigidity in soft layers and durability of brittle ones.
If using it for armor I am pretty sure you could make it a lot thicker and still be lighter than steel. I'm sure most people know this already, but how the layers are laid out matters. Just like how I've seen people making bullet proof plates out of fiberglass and epoxy, orienting each layer at an angle to the previous layer made it stronger.
there's a company who makes camera equipment and accessories for camera rigs called smallrig, they make 15mm carbon fiber rods at varying lengths. if you were looking for something to chop, those type of rods are probably reasonably priced to do testing on
The delamination issue could probably be solved cheaply by drilling a few holes and putting pop rivets in strategic places.
One could also vastly increase it's armor value without increasing the weight to much by using cheap metal strapping with holes to run a mesh across the armor, makes it much stronger vs bladed weapons but doesn't do much for arrows, the attachment points then serves the same purpose as the pop rivets.
get some rest Shad, we love you guys
the foam would act as a frangable layer to absorb shock, but once it cracks, it's not providing protection; in the same way as motorcycle helmets do. aka, you get one hit in any area before protection is significantly lost. There'd need a different solution, esp since sowrds and shock go together
The only way to tell the truth is to speak with kindness. Only the words of a loving man can be heard.
The thing with carbon fiber is that it’s strong *per-unit-weight*. So really, to compare apples-to-apples vs an equivalent steel product, you’d have to give the carbon fiber enough layers/thickness to give it an equivalent weight to the steel. This is more fair.
So, start thick on the carbon fiber, then dial it back to the point where you are realizing the weight savings again, but still stronger than the steel.
You would back a metal sleeve or armor with carbon fiber. The metal has a higher hardness making cutting into it harder, the CF is stronger and prevents the metal from caving or breaking on strikes, especially if the CF is more flexible. Maybe D30, or similar reactive material, for shock absorption.
I would go with a sort of steep V shape of metal over top of the carbon fiber for the blade otherwise the carbon fiber around the blade will get worn away when you hit things with it.
Something I remember from when I was a kid was a character who’s used a sword and its metal scabbard as an off hand parrying weapon, how practical would that be?
