How To Make Carbon Fiber Tubes - 4 different techniques (Tutorial)

Explaining 4 Different techniques to make Carbon Fiber Tubes:
- roll wrapping prepreg
- Braided carbon fiber sleeves
- Split mould tubing
- Filament winding

ex aerospace filament winding manufacturing engineer here. I worked in the industry for around 10 years before moving 4 years ago.

Happy to answer any questions you may have which x winder weren't answering if it was technique based.

I wanna build an f1car this is gonna be one hell of a project

I've had great success with heat shrink tubing from Soller composites. The epoxy-resistant tubing shrinks down and squeezes out the excess epoxy. Makes a perfect tube!

Love the look of the last one but the first one seemed to resonate as best beginner choice . Thank you for the video.

The most innovative way to make a carbon tube is to simply roll the tube and just fill the tube with loose carbon fiber all in the same direction already with resin, done. Don't even bother with vacuum. Ocean Gate approves

[davidscott]

I was taught to wrap the tube with 3 layers of tape. The first at medium tension, then tight, then medium for the last wrap. My favorite material to make tubes from was a knitted triaxial carbon at +45, -45, and 0 degrees. I made a 59cm frameset that weighed a little over 3lbs with it, the forks weighed right at 1lb.

such a useful video thanks so much dear mat I learned so much from this video especially about putting the aluminum mold in the freezer for releasing from the part

Hi Matthieu, I love your videos! Keep them coming!! I would find it really interesting if you could compare the stiffness and strengths of the different methods, I would appreciate if you could do some impact resistance tests of composites too if you have the time! Great video as always.

[ChrisCraigie-oiun]

Outstanding presentation! Thanks for the great video and the explanations of the different techniques. Great job.

[terjegjerstad]

Thank's for showing. I have been watching Easy Composite and you to get an idea how to make the main beam on my laser cutting machine. It's not easy to find exactly the dimension I want and strength in the directions I want 😉🇧🇻

Will there be a video on stress testing these 4 types of carbon fiber tubes? (bending and compression) I would like to see which method gives the best results. Or it would be surprising if the results from the test is uniform across the board.

[HitAndMissLab]

Now that you found the time to do this video, can you please make another video explaining how to join carbon fiber tubes at right angles, obviously without loosing strength. Yeah, and joins can't be made by simply wrapping corners up, because that will reduce grids to only one size.

[Reptile]

Also great video Tutorial, if anything I will be making my own filament winder. After doing my research, it would have been cheaper to make your own with bigger motors to wind even faster.

I like your ideas, use to work for profile composite/ profile manufacturing building shafts for the paddle industry and prototypes in the lacrosse field etc. Looking to make a special layup blow gun. I see wil need to get larger oven for what to make

[micahdemahy]

What kind of shrink tape are you using? with the exception of the split molds is there a way to remove the aluminum pipe is there are bends in the pipe not allowing the pipe to slip out from the carbon?

[magnuswootton]

these are good for epicly strong robot legs.

[lukpo]

There is also another way. Just doing it with wet laminate and vaccum.bag the tube. Great video!

[xushenxin]

for high strength, you need to suck vacuum from it. So that 14 psi from atmosphere pressure will be applied to the part to increase the strength. For thicker part, 14psi is not enough, you need to suck vacuum and put the part in pressure container to apply additional 60 psi. If no pressure, there will be random small distance between the fabric.

[frankbraun]

How about strength testing for each method. Thats wasnt really discussed in the summary.

Great Video! Do the tubes have good circular runout? What is the best technique to achieve the highest circular runout without reworking it?
