Why not make it out of the structural fiberglass and put the carbon fiber as the final layer? Also, part of kevlar's strength is that it is offset by something like 45 degrees on each layer. If you haven't already, you could implement that technique into the structural fibreglass as well--it may affect the tensile strength by layer.
Will the joints Of the suit be covered on a kevlar composite?? Also, how about a different epoxy that graphene from the flash graphene is added, maybe that the missing piece? From what people said of putting graphene, if added to concrete, it will increase it's strength.
All your videos are 100% gold, they are so informative and cool, pushing the limits as to what is possible. You outperform the hacksmiths exoskeletons like it was butter! Its so cool! Love it! And im looking forward to seeing the progress.
I've done something similar for strength testing, but on smaller scales something that I have found works is to attach the wire/string to the load point at one point and a bucket for holding water on the other, then slowly add water until the test part snaps then weigh the bucket. A bit slower, but more exact than the lifting weight method and cheaper than a load sensor.
One thing to consider is if you want the nice cosmetics of the beautiful carbon fiber, but still want the cost/strength of fiberglass or kevlar, you can simply use the stronger material, then put a single layer of the pretty stuff on the exposed surface. Might be obvious to some, but it's often overlooked.
Alex great job again I am a very old subscriber and I really love how much you have progress on this project. I hope to finally find a big sponsor because you are the only one that I know who is so accurate and close to create a realistic and factional suite like this. Great job again and keep going!!
I only just saw your latest video by chance. TH-cam suddenly stopped recommending me your videos after part 1 of this series. Glad to see you back though. I appreciate that you never post videos for the sake of releasing a video, each video shows something with purpose.
@@ALEXLAB yes, one of your shorts popped up for me. I saw it was from very recently, so I went to your channel and saw there were three whole videos that had slipped by me. I've watched all your older videos, and so used to get each new one in my feed when it released. Sad to see this happen, and I'm sure it's disappointing for you too. Best of luck.
the addition of uni-directional fibers and kevlar behind the carbon fiber makes it work well as a protective suit, ive been testing composite hybrids and found that combo to work well. the cf does its job by dispersing the kinetic energy and kevlar softens the blow, especially when used with a more flexible epoxy. you can use softer tpu and a grid type infill but printed horizontally not vertical like you would normally, it acts as a good buffer for shock of the impact. give this a try and good luck with the project, the cf could be used as a replaceable panel, btw, for simple repairs if needed.
To add a little to the conclusion, fiber glass (S glass) is "stronger" than carbon fiber. Fiber glass can withstand more tensile load than carbon fiber for a given weight, Kevlar is even stronger than that. Even if you use E glass (what more people use when they use fiber glass) carbon fiber is only about 20% stronger. If the force is in compression Kevlar becomes much weaker than even E glass. Kevlar does however have very good abrasion strength compared to the other two. So if you plan on sliding across the concrete Kevlar is a good option Carbon fiber is by far the most "stiff" of these three materials, which is why its used on lots of race cars, because the shape of an element is important to keep. Carbon also has very little "elongation" compared to S glass or Kevlar, so if something is very positionally important Carbon is the way to go.
Good luck with the suit. Love your work so far. I have no experience but remember once saw a layering of carbon fiber (and possibly fiberglass and maybe kevlar weave) was done with a rotation of the layering resulting in stronger mesh for car part. I would recommend a small test with a rotation of 45 degrees to purposely misalign the weave...hope you try it and see if you get any benefit for the suit build.
I am not sure you correctly factored in the different thicknesses of your materials, since you didn't go into detail on your calculations. Just to be certain, the correct formula for the bending resistance of a rectangular crosssection is (Width*Thickness^2)/6. That means for double the thickness, you would expect to see quadruple strength in terms of bending load. Did you calculate it that way? Because I am suprised fibreglass comes out at the same strength as carbon fiber. Also, consider apllying pressure to the part while the resin is hardening, for a higher density of fibres and better strength per thickness (weight) in the finished product.
Can we please get an update video on your lightsaber? I would be very interested in seeing a tighter laminar flow (I've seen it done with a MIG welder tip), as well as what would happen if you arc the high voltage from a stun gun into the blade. Please?
While I'm note entirely comfortable giving complete technical info on an open youtube channel, HDPE as a body armor substrate should not be dismissed. Depending on your needs (assuming ballistic?) density and weave retention under deformation are critical parameters to consider, and why kevlar has been the 'gold standard' to date. I know there is some advocacy for ceramics, but the downside is that they only protect/work Once and must be replaced after impact. On the other hand, if there's a death squad approaching your house and all you have are floor tiles, they'll do an above average job (ahem, Once!).

Have you tested carbon innegra hybrid. or Basalt innegra hybrids. For armor they may be better. They are not going to break like the carbon. Good strength with good flex means they will aborb a lot of impact energy. Carbon innegra would be even lighter than carbon alone
What happens if you use a regular black fabric for non critical applications, instead of fibre glass ? Should work ? Some fabrics might be even more easy to stretch, give similar visual effect as carbon fibre, just with much less strength ?
You need some kind of advertising or help with the youtube algorithm. I can guarantee you people will subscribe. I saw your videos for the first time today, some guy made a youtube short promoting you which is why i looked you up and subbed. Any frequent youtuber would be stunned to see you with anything under like 5 mil subs. Way to many marvel fans out there.
Hello from Tokyo Alex! Big fan. I have a project that required a custom shape 1000psi tank… I’m hoping to use a a similar technique. The make the tank, would you know how many carbon fiber sheets would be needed for 1000psi? 800psi is CO2 gas. I am also assuming they the 3D print coins simply be the “inner” shell and reinforced by adding the epoxy plus CF sheets over the 3D print? What would you advise?
I think you're going to eventually have to get your knees replaced from the extra stress you're putting on them while riding your electric unicycle. And, knowing you, you'll have one knee in one material and the other in a different material and you will post your analysis of each material's performance.
@@pitrek121g they wouldn't stab you because they fly outward. And you do wear car on your body. You sit inside a car, so it goes without saying that the car wraps around you
What are you taking about? Since when cars use shattering as protection of the occupants? It's completely the other way, modern cars use corrugated steel or aluminium crash structure that will deform, not break, thus absorb as much of the force created by impact, as possible.
@@Failer__ consumer cars use metal as a crumple zone. Race cars shatter as a crumple zone. Look up "WHY DO F1 CARS BREAK SO EASILY". Either way, it's obvious that shattering requires energy
Ask technical questions here 👇
How about HDPE or UHMWPE/Dyneema?

You need shallow angle lens, and position camera further away from the ruler, to decrease perspective distortion.
This way your measurements will be more accurate
Bro every word out of your mouth flies over my head, but this is so cool could not stop watching!!
So glad I realised you had returned! ❤
Some one get this man a contract, workshop, and grant!
Always happy to support an earnest, and dedicated, scientist as much as I can. Liked and commented. 👍
I'm loving the consistant videos keep it up!
hey alex, this suit you talk about is the ironman suit ? im happy to see you back!!!
I love that "Нихера себе" at the end of the video 😄 Great job, I hope you will get the kevlar for your suit 👍
Exciting ! Definitely experiment with different weaves !
Lets help alex for the Kevlar!!!!!
This video is amazing! Thanks so much for sharing all this info dude

12:10 what is the weight of carbon fibre and glass fibre samples you used in this test?
great video would also be interesting to compair different bonder as that plays a big part in the stiffness and brittleness of the part
3d printed titanium about half a inch in diameter thin plates over laping the 6 layer of kevlar
Imagine just combining all of them and getting a super composite
Amazing work
What about flying system like iron man
I have a project i want to build but im now as knowledgeable as you, was wondering if you could help me out .
Amazing work as always!!!

Check vaccum infusion of resin, stronger and lighter tgan your method
Maybe 3d printed thin tungsten plates would be best for the chest but it will add weight and cost, kevlar is better but still expensive.

shattering is good. it means that the energy of impact is directed away from the body. that is exactly why cars use it.
You don't wear car on your body. Shattering parts aren't good when they can stab you.
