Explaining 4 Different techniques to make Carbon Fiber Tubes:
- roll wrapping prepreg
- Braided carbon fiber sleeves
- Split mould tubing
- Filament winding
For part 2 finishing the tubes: • How To Finish Carbon F...
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
PART 2 Will be uploaded 15-09-22
So faaaar 😩 but we will be able to wait for the good content 😌
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.
Hi! thanks for your comment! The X winder is good but has some limitations, the biggest problem is the carriage. I'll re-design it with linear rails and lighter weight in the future. Glad to hear I can come back to you for more information!
Love the look of the last one but the first one seemed to resonate as best beginner choice . Thank you for the video.
Outstanding presentation! Thanks for the great video and the explanations of the different techniques. Great job.
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.
Hi Matt great video! I was wondering if your vaccum pump is running during the whole curing process? If not how do you keep a high vaccum level in the vaccum bag ? Thank for your answer
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!
Thanks for the info!
@@MatthieuLibeert have you ever attempted to test the tubes done in different ways under a hydrolic press or bending forces? Would be interesting to find out if the technique affected the final strength of the tube!
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.
Thanks! Great suggestion, will see what I can do for future videos, as not all of these tubes were made in same thickness it might give some information that wouldn't be correct!
hi were u abl to get this orted out
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
Glad it was helpful!
Excellent. Thank you.
Nice work!!
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 😉🇧🇻
Thank you so much. 🙏
Bonjour matthieu, très belle vidéo avec technique...bravo
Merci !
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
Amazing thanks. 👍
Glad you liked it!
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?
Great Tutorial
Thanks! See you in the comments on the next one, next week 😉
@@MatthieuLibeert You can count on it
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.
Shouldnt be to hard to make, the hardest part is software in my opinion
I wonder if the X-winder can also work with square tubes and profiles. I also wonder if CF tape can be used in the X-winder.
Hi, thanks. Very informative! I'm loooking for techniques of making large diameter tubes for telescopes. In range of 30-50cm in diameter. I think it can be done with the winding method.
Yes correct, should be posssible!
Great Video! Do the tubes have good circular runout? What is the best technique to achieve the highest circular runout without reworking it?
Great videos!! Congratulations ;-)
Muito bom
Hey Matthieu thanks for your great video. I just have a small question, I would like to know what kind of tape do you use in minute 02:04?? If possible could you please tell me which one did you use or probably write the link to buy? Wish you best luck and a great day
Hi Matthieu, how long and how many degrees of heat during carbon prepreg in the oven,please answer
Nice video thanks! 👍
Thank you!
Good info
Thank you for information
Welcome
Ever thought of positive pressure in split mold tehnique, inner tube put on pressure?
Hi There Thank you for the video techniques with carbon fibre I have a questuon Hiw would you approach a conical shape 40cm diameter 30cm height Maybe one sheet to cover it all ar once or in pieces or any other way Much apprieciate your help Best
How do the strength and stiffness of each technique compare?
Great video! For those of us in the U.S., any recommendation as to where to buy materials? In particular, I'm looking for carbon fiber sleeves and heat-shrink tape. Thanks.
Composite Envisions has both. I have had excellent service from them in the past.
Which method is the best in terms of strength and stiffness? I've seen videos of driveshafts being made by means of tow winding, but is it because it is the strongest, or because it's more difficult to use weaves to make long driveshafts?
hi, how did you make the mould for the split mould tubes?
Where can I get the carbon fiber that comes in a hose?
Hi Matthieu, I always watch you procedings with great interest and find them very very educational and informative. However, I would like to present a problem in regard to carbon tubes. I am an avid model airplane flyer and builder. I would like to make a wingtube. In this case a tube that has an outside diameter that exactly matches the inner diameter of the existing tube that is in the wings. Is there a method or technique to do that ? It would be very much appreciated if you could offert some advise.
thanks awesome! seeing your name you must be dutch or belgian (would rather think dutch) :D The best way would be to measure out the inner diameter you want for your new tube, buy an aluminium mandrel (with your inner diameter you want in carbonfiber being the outer diameter of this aluminium tube and make a tube on this mandrel). Might be hard to explain on here but I guess it's possible to understand?! :D
@@MatthieuLibeert Hello Matthieu, thank you very much for your reactiom/answer. I confess: Dutch 🙂. I understand but I have to account for the lay-up thickness. This is where the problem starts. The tubes have to fit without ANY play. It must be an exact fit. Perhaps I should make 2 tubes that fit into-each other and glue the larger one into the existing tube of the wing. Hoping I will not add much weight by doing that... Then there is the question of how to make tubes with exact dimensions with very small tolerances..
nice presentation M.
Thank you kindly
Have you ever made a rear superkart wing?
In the split mold method some aerospace companies use inflatable bladders to maintain a constant surface pressure. Very expensive
Who the split mold process be the same if I were to joint two ends together at a corner? Like for a front car splitter lip or a rear car diffuser. Those parts have complex shapes that can’t be don’t in 1 pieces of carbon fiber so multiple pieces of carbon fiber are used.
Obrigado amigo
Thanks! I dont speak portugese but I understand this :D
Good Video! :)
Thanks 🤗🙏
Could you advise on how to make square tubings
H Matthieu, any alternative on curing process without oven?
Do you have video for repairing broken fishing rod?
Amazing! Thanks a lot, Matthieu
Cool, what's the diameter limit for this technique if the 220g twill 3k carbon fiber is used? God bless.
add more words to your question....dont be lazy and i might give you the answer
@@lunam7249 rearranged :-)
There is also another way. Just doing it with wet laminate and vaccum.bag the tube. Great video!
awsome
Thanks!
Is it possible to have make tubes that have threaded ends? I want file a form 1 to build a silencer and this would be an awesome way to do it if I could screw it on a barrel and put on end caps.
Yes it's possible! you can add threaded ends by gluing in an aluminium thread on the ends of the Tubes, won't be featured in next video but might do it in a future video maybe 🙂
Hi friend! You have a tutorial carbon wrap manual?
what shrink wrap are you using?
Dear sir, what the material require to complete carbon fiber. i am not clear on. pls help and recommend me.
I take number 3. do you think you get peel ply out of the tube? Got 60mm outside and need a good as possible surface inside
Should work... If you can get the start you might be able to get it out I think
SOrry first time I see the enclave bit... where can I learn ,more about this....?
What cycling industry technique they use??
Hello, Will it be possible to make a carbon fiber tube with open structure (porous), such as a filter?
Would be possible but not like surface porous, you could cnc drill a lot of holes if needed
What gives CF it's strength is that it is a composite material with a resin. Also drilling holes will limit the length of the fibers and that reduces strength.
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.
An out of autoclave prepreg was used here for the splitmould tube. So -1 Bar which is enough for this prepreg. You are correct with the pressure but not everyone has acces to autoclaves :D so this is giving decently good results but if your looking for parts for F1 or out of space you'd better use an autoclave with pressure as well
Great Video again. Could you please tell us what shrink tape you use and where to buy it?
It's from Easy Composites as well, you can find it on their website 🙂
What about the split technique, with continuous fabric? Wrap the fabric around a rod, that is much smaller than the split mold, stick it trough and unroll into the mold. Finally put like a bicycle inner tube into the mold and pump it up, to apply pressure against the fabric.
Which is the lightest and strongest tube? Taking into account the thickness. Thank you.
Thanks for your comment, as all tubes were made in different ways it might be something hard to compare. Due to the many comments on that topic, it might be something intersting to do in a future video!
@@MatthieuLibeert yes!! Make a video :)
Can you make AR 15 handguards??
these are good for epicly strong robot legs.
Hi friend! Good job! You maker a turning metal?
Hi, no I don't turn metal 🙂
@@MatthieuLibeert lathe base openbuild
How do I scale this up to make a 10 metre mast for a sailing boat?
You could buy a boat for the investment needed to scale this up to 10m long 😁 there are some companies specialized in just making big and long tubes for specific applications
There is a “How It’s Made” episode of that. Good episode.
What is for oven ?
This guy sounds exactly like David Windestal from flite test!
How does one make a 5 foot long tube? As an example, say a paddle for boating?
You can use lost casting methods with CF. Or you can simply wrap the CF over a light weight structural material that you don't remove afterwards.
Hi, what kind of shrink tape do you use?
It's the one I bought from Easycomposites. If you need specific information about that tape you can always try to contact Easycomposites, sure they'll be able to help you out
@@MatthieuLibeert thx
Is it precize for the inner diameter?
depends on different techniques. The split mould will give you perfect outer diameter the other techniques will give you perfect inner diameters :)
Don’t bother contacting X-Winder, I have been hoping they would fix some of the issues I was having, but I think Turner Hunt no longer sees any need to make any more improvements to the winder.
And what about shaped tubes with clear finish on both sides?
Will show that in the next video, you can finish the shrink tape side to a good finish as well with some care 🙂 the mandrel side will already have a good finish
@@MatthieuLibeert I mean like prepreg refueling s shaped tube with same thickness of wall on whole part
Did it in another tutorial with the 3d printed moulds and silicone expanding core, there youll get a finish on the inside and outside
*Hello my friend 🇧🇷❤*
Thanks for your comment!
What is the strength of braided carbon fiber tubes?
strenght is hard to define by numbers, it is strong on 45° so torsion, less on bend and stress
very strong...1/2 aluminium by wieght and size, in this tube form.....in perfect orientation 40 times stronger than steel!
PROBLEM : I am going to make a GOAT Single Seat Glider. Its an AL tubing 6061 T6 structure all arround. In India we have NO SOURCE for 6061 T6 Al tubing especially the sizes I need....and importing is mental. SOLUTION ? CF raw material is available and raw material infact is also easily importable ... So make the Tubes out of CF QUESTION : For a given size of AL ...how do i figure out the EQUIVALENT CF solution ? MEEEOW???
Wil je mij een keer helpen met het bekleden van mij e-foil blank?
Heb ik niet meteen ervaring mee 🙂
@@MatthieuLibeert Jammer :-(
the name of the plastic wrap, sir
Existe uma técnica de molde por fora e bexiga por dentro?
sorry I don't speak portuguese :)
@@MatthieuLibeert everything OK my friend. I'm translating this message in Google translator. I want to know if there is any technique to do everything with a curve using a ppr bladder inside and mold on the outside. sorry if i couldn't be clear and thanks
Thanks! Yes it's possible, bladders are a common thing in the composites industry!
Разве можно что нибудь изобрести в такой чистоте?
I used a waxed pvc pipe for my wet layup. I then got it off by putting in freezer.
correct works well with pvc tubes as pvc releases pretty well from epoxy
split mold seems like it would be weaker
it does huh?, it is
The last method is like making kokoretsi!
Didn't know what it was and had to look it up, looks like that indeed 😁
Türkiye language pls
There is a nicer way of sealing the bag using 2 pvc pipes. (assuming it is a bag with one open end) One is C shaped, the side is open. You wrap the plastic around the pipe, do not roll it. Clip the C shaped Pipe over the plastic and pipe. Your done and can re-use this over and over. The closest example I can think of is a woman's hair curlers. But there is no need to roll the 'hair' around the curler, just a wrap.
Have you found any video's of this process or websites explaining this? I'd really like to see it done in practice as I'm not 100% clear on your explination. I understand the hair curler comparison but I'm not sure about the bagging & plastic wrap part.
Hi Dave, thanks for your comment! Not 100% sure I know what you mean as well, do you mean you put a pvc tube diameter on the inside of the bag, then clip on a c-shape pvc over the bag and pvc tube that is on the inside of that bag to seal it of? If seen it being done on ends of bigger vacuumbags but not sure you can get it fully leak free that way, mostly seen it used in veneer wood bending with vacuümbags, where vacuum doesn't have to be 100%

Carbon fiber cracks very easy under any strain, just ask the titan sub crew, O I'm sorry they're dead.
Dude please wear gloves when handling CF

Извини дружище, но трубы ты не умеешь делать от слова совсем . Ахинею нам показываешь, лапая жирными руками припрег и засовывая потом изделия в холодильник . У тебя вообще есть образование серьезное в этой профессии? Такое впечатление что тебя взяли с кассы супермаркета и поставили к бочке с эпоксидной смолой -)))
