So faaaar 😩 but we will be able to wait for the good content 😌

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!

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!

Glad it was helpful!

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

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

Glad you liked it!

Shouldnt be to hard to make, the hardest part is software in my opinion

Thanks! See you in the comments on the next one, next week 😉

@@MatthieuLibeert You can count on it

Merci !

Thanks 🤗🙏

Yes correct, should be posssible!

Thank you!

correct works well with pvc tubes as pvc releases pretty well from epoxy

Welcome

Thanks! I dont speak portugese but I understand this :D

Thank you kindly

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..

add more words to your question....dont be lazy and i might give you the answer

@@lunam7249 rearranged :-)

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 🙂

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.

Should work... If you can get the start you might be able to get it out I think

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.

Didn't know what it was and had to look it up, looks like that indeed 😁

Composite Envisions has both. I have had excellent service from them in the past.

it does huh?, it is

Thanks!

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!

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

It's from Easy Composites as well, you can find it on their website 🙂

Thanks for your comment!

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 :)

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.

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%

Hi, no I don't turn metal 🙂

@@MatthieuLibeert lathe base openbuild

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!

depends on different techniques. The split mould will give you perfect outer diameter the other techniques will give you perfect inner diameters :)

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

Heb ik niet meteen ervaring mee 🙂

@@MatthieuLibeert Jammer :-(
