Gaaf project, heel mooi om zo lichtgewicht carbon vleugeld te maken zonder buitenmallen. Helaas is de leading edge van de rudders niet ideaal op deze manier, de lucht laat bij een kleine hoek al los. Het dikste punt moet ongeveer op 30-40 procent koorde liggen. Dat scheelt een factor 3 weerstand en 25-50 procent meer lift. De kromming moet t scherpst zijn op de neus en geleidelijk minder worden naar achter toe.
Nice! I love that you encapsulated the 3d print with the fiber. I was thinking about that recently and 3d printing would be great for one off molds vs those foam plugs traditionally used for fiberglass. Not seeing a whole lot of people doing it though oddly.
OP, I presume you're talking about using the 3d printed part as both mold and part of a composite construction... I've been looking for more of this too as I suspect it's heavily underutilised ;-)
I'm assuming you're speaking Dutch. I love Dutch! I'm a native English speaker and can also speak German, albeit roughly. Dutch is so fun because I can understand so much of it with those other two languages under my belt! I was especially amazed when I went to the van Gogh museum in Amsterdam and could read all the signs! Awesome project, man
Airfoils can easily be shaped of foam with a hot wire and a wooden template on each end. This technique has been in use for decades in experimental aircraft and gives a better result.
@confusedsoul24 that’s great, keep doing that! In fact, why don’t I send you a CAD model of one of our newly developed airfoils so you can give it a try, and I’ll get back to you in a year. Because that’s probably the time you’ll need to get it done.
@@rykerhasyounow because the foam is uniform in stiffness and bonds a lot better to the skin. Epoxy does not bond to PE or PVC thus you will have issues with skin delamination. Heat expansion may also become an issue, depending on the application.
@@spearhead3496 If it is such a complex airfoil shape like helicopter rotor blades for example you're better off creating a mold from the 3D printed part. Then all internal structures are laid in the mold and then filled with epoxy foam. After demolding the scructure is skinned with carbon. The only use of 3D-printed cores is with actively moving airfoils, but then the fibre alignment of the carbon calls for the application of filament tapes, but that's a whole other level of complexity than what's shown in this video.
@@spearhead3496 We've made thousands of wings exactly this way and it does work better. Incidentally it's also faster to foam cut cores with a hot wire than the 5 days of printing, especially for anything remotely larger than a squirrel.
@@Thepracticalengineer I agree, subtitles were excellent! I absolutely love that TH-cam is a platform that facilitates knowledge sharing across language barriers.
Hoi, tipje: als je een betere hechting wil op PETG kun je bij HP-textiles een epoxy primer kopen op PUR basis. Daarmee hecht het super. Zonder trek je je weefsel zo van je printje af. PLA werkt het minst goed, slechte hechting en vervormd in loop vd tijd.
Hello! like your work! Following comments are not intented to blame, but to help to do better, no offense: - honey comb do not have big structural resistance in this axis. It is very strong for crushing effort in the axis of the combs. Think about a cylindrical glass (to drink), in which axis will it handle the most of effort if you walk on it? In this case I think that triangle pattern would handle more effort (which is finally almost what you did with this big honeycombs ;)) - not physical but my way to do: when you flipped your making tape I already knew the result with painting. Do not overlap masking tape as possible. In that case I personnaly let the masking tape "floating" on the trailing end, then make it meet the other glued side end. More like a pinched U shape (or drop) than a O shape (coil). No overlap then and no air gap where paint loves to stain. Hope I was clear enough with my poor english ;) And I hope you considered it as an advice more than a lesson ;)
Hoi, bedankt voor je video. Ik had nooit gedacht dat carbon producten maken zo eenvoudig zou zijn. Ik ga dit zeker gebruiken bij toekomstige projecten. Hoe kan ik het best bepalen welke mesh ik moet gebruiken voor mijn ontwerpen?
Welk carbon weefsel bedoel je? Hoe dikker het weefsel hoe minder lagen je hoeft te doen en makkelijker het is om vlakke of enkel gekromde delen strak te krijgen. Dunne weefsels kan je makkelijker in en om bochten krijgen.
Great work, I used to work with fiberglass and I find the carbon fiber so interesting. I though it was more complicate to do but there is a dub surrounding my head, once I saw in a F1 channel how the engineers construct the chassis in carbon fiber, then they put entire chassis in a kind of “chamber” so, what´s the different?, it is for the size of the piece? Thank you
Heb je berekent hoeveel kracht op het luchtroer komt? Ik vraag mij af of je met een iets meer wall dikte en wat epoxy aan de buitenkant ook voldoende zou zijn. Al ziet dat natuurlijk niet half zo gaaf uit :p
My understanding that a well fabricated and properly sized carbon fiber piece has similar rigidity to steel. Yet i don't see people making DIY mills, routers, lathes, drill presses with even partial carbon fiber parts. The majority of none industrial metal working machines use aluminum extrusions for most of the structure except the base and supports. I assume it's too niche and not very practical or i might have misinterpreted the specifications of the materials.
Make something from a weave of homemade carbon...use high tensile strength material & resin , compare it to fibre glass & real carbon...few videos exist of real attempts at home made composites...they're just making stuff with composites not actually making a composite material..
Een paar videos maken die een heleboel views krijgen.. Tot een jaar terug maakte ik mijn videos in het engels, een deel van de subs is dus ook engels sprekend en kijkt niet meer de videos.
Great video and very useful! Didn't know the safety part even after watching a lot of carbon fiber videos). I plan building a carbon fiber vertical wind turbine that combines 3D printed parts and carbon fiber. I got a little brainfucked when I tried to translate in my head, thinking you speak in english. (english is not my native language).

Plenty of people doing it. Easy composites even has a video about 3D printed molds.

How does it give better results? Printing seems faster and would be close to perfect.

Simply Fabulous! However, I almost lost you when you put on the white jumper! Get some sun Bro!!!!!
I need a pair of rudders for my hovercraft. You have inspired me to give it a go.

The chamber is an autoclave it heats up and pressurizes. It's for use of prepreg carbon and also improves the mechanical properties

Nice work
good job
Heb je het 3d geprinte ontwerp nog ingesmeerd met wax? Zodat deze makkelijk los kwam van het oppervlake ?
Nee, het idee is juist dat de 3d print er in blijft zitten
Are you from South Africa?
This work with the carbon fiber is how the fiberglass..?
Wouldn't it be better to use PVA, wrap it with fiber and resin, and then dissolve the PVA away?
Long thought about that method, have you ever seen it done for layups?
How did you make the honeycomb pattern within the part?
I'ts 3d printed
did he keep the 3d printed material inside?
yes he did
what is the thickness of 3d printed wall of the airfoil?
If I remember correctly it is printed with a 0.6 mm nozzle. Zo on most places it's 0.6 mm and in some it's double that.
What about the point where the tube connects to the blade? Zero strenght there?….
Hi! Could you say the ref. Of the cnc ?
Try Topology Optimization
The mold should be removed for better efficiency or instead u can use styrofoam as a mold which is light weight and works perfectly fine.

Was het niet beter om het roer te vacuumtrekken met een vacuumzak?
Jawel, eigenlijk wel maar ik heb dat niet en wilde laten zien dat er eigenlijk maar weinig voor nodig is.
How much strength does the carbon add to the structure?
Like 5
How much lighter is it?
love your blouse how many bph (bananas per hour) faster is with this wing?
what kind of bandsaw blade do you use to cut the carbon fiber?
Its just a fine toothed wood blade
Het is een HOVERcraft...geen HOEVERCRAFT :)....als je het uitspreekt als hoever...is het een stofzuiger
Zou je dit eens fonetisch willen uitschrijven?

Carbon fiber is an expensive build process, so will never be economical compared to aluminium extrusions when the latter has enough strength
Nice
Thanks!
I need profile to modelplane 😊
Kopen is goedkoper 🥴
