man, this company makes some really REALLY high quality tutorials
I had the pleasure of speaking to Paul this afternoon about my project and the use of carbon tubes / wrapping carbon tubes around foam core to make a strong space-frame and the shear amount of knowledge and information he gave me was astounding!! Several really good ideas and new takes and new techniques I hadn’t even considered. I’ve ordered materials from Easy composites in the past for glider and boat repair work and I’m really looking forward to working with Easy Composites on this project too!
Thanks Paul!
Glad we were able to help.
"i am gonna be doing a very primitive test"...moves on and using an industrial press with a pc program that measures the force in detail...epic
nice video btw
Thanks Dimos. OK, so maybe 'primitive' was understating it a bit but what we meant was that we were not going to get right down into test standards and things, at least not in this video.
a primitive test is also, often a stress it till it breaks kind of test, or destructive test just to measure maximum capacity:>
@@easycompositestv I really appreciate the tests at the end. I've worked with and used carbon fiber in the automotive race industry (Renault spec racers) and years ago we used to make some components out of carbon fiber, but i never really got to see it tested like this! We all know it's strong but hard to visualize sometimes.
We only used it for Naca ducts and some basic non-structural things.
@@easycompositestv Before failure mode is achieved is the material in the elastic domain like steel would be before it reaches plastic deformation? Otherwise said, if the part is released from the machine after reaching 600kg at 10mm deflection would it still have the same dimensions as before being subjected to the test?
Haha yeah it's primitive in terms of test design, but the equipment is $10-20k and up. I've done the same type of test with static weights to the same effect, though. You don't need the fancy tensile tester, but you would need to build up a fixture for the test.
These videos are the best thing I have seen online in my whole life 😮 which has been long, half a century unfortunately 😢
Always amazed by the quality of your tutorials and products! You deserve a lot more subs !
Thanks Youssef, haha, well, it's pretty niche stuff that we cover. If we were talking about Minecraft, Tik Tocking or giving away $100,000 to strangers then we might have a few more subs but when it comes to technical manufacturing there's only so many viewers out there!
@@easycompositestv 0ver a third of a million views though. Almost viral.
@@markrainford1219 it's pretty impressive tbh but the number of people who need to learn to make carbon fiber AND don't work at a manufacturing firm who already makes carbon fiber is pretty slim unfortunately. Awesome videos, views aren't everything though
Thank you for this, guys. I really appreciate this great material.
You're very welcome!
Thank you for adding more videos. It’s great of you all to keep sharing your knowledge! It’s very much appreciated.
Our pleasure Caleb, we have more coming and lots more ideas to share one they're done too. We really enjoy helping to explain these processes and share the information.
Thanks for another great video, I really wish they were produced more often!!
Thanks Jon. Yup, so do we. We do have a more frequent release schedule coming up, hopefully we can maintain it.
I was really fascinated by the tube and when he put it in the machine I nearly cried
thanks for the video!
omg I cried too😢🥺😂☺😘🤭😐🤤😪😐😏☺🤭🤪🥲😐😶🤤
This great info, and easy for beginners.
A beginner's playlist would be a great addition
Thank you so much for actually showing some tests and discussing numbers even a little bit. Wonderful!
Yes, agreed, more numbers would be good sometimes. They're not everyone's cup of tea so we don't tend to go too heavy into figures and calcs but we have at least a couple of videos in mind that will dive a lot deeper into material testing and comparisons. Stay tuned.
It’s so pretty! I can’t wait to try and make body panels for my truck.
same here
Good luck buddy
Your truck weigh like 3 tons and you make light weight body panels for it !?!?!
Damn carbon is hella strong 💪🏽 that’s amazing
Great video! Thanks for sharing all these different methods with us over the years!
You're welcome Benjamin, thanks for watching over the years!
You guys make the best product videos..
Love your content, it's amazingly information dense
Thanks Srini, *information dense*; yes, I guess that's what we aim for!
@@easycompositestv Yeah! Nailed it carbon bois!
I use that carbon tube for spacer for my bike stem.strong and very light.
Thanks for adding those little tid-bits about how large manufactures might do things. I'm involved in manufacturing but not yet into carbon fibers.
I used this video as inspiration to make my own aero bicycle seatpost and it works great. Thanks for these awesome videos!
Great to hear!
Since the beginning of this channel, these are the best carbón fiber manufacturing videos around RUclips, no doubt. Keep the good work!
Thank you very much Adrian, it's great to have had you on board since the start.
great video, PS: for the novices among us a mandrel ( not a mandrill- monkey family) is a rod of metal you mount between centres in a metal or wood lathe to hold a round part securely ie a pulley or donuts shaped object, the rod holds the part by the inner bore so machining can occur on the outer surface ( otherwise gripped by a chuck, held at a centre, etc.) as this is the only way to hold it and machine successfully.
I work for "Extremely Difficult Composites™" and 'we now realize' what we've been doing wrong all these years. Thank you!! You guys really R the "Carbon Fibre Whisperers" Cheers!
Ah it's all in the name. 😅 Glad we could help.
i like that you took time to show how to do it right :).
I am addict to this videos! AHAH , respects from Uruguay
Thank you Pablo, great to know we're reaching far and wide.
Great vid. Do you account for the thermal expansion of the aluminium mandrel when you consider what ID of the tube you want? I assume that the expansion of the mandrel "overrides" the contraction of the composite shrink tape. When calculating expected wall thickness do you assume that the consolidation will be more-or-less equal to that achievable using vacuum processes?
For size critical applications you would have to take into account expansion at the cure temperature of the pre-preg. The compression provided by the tape ends up being similar or slightly greater than a typical vacuum bag. However, the fabrics can only be compressed by so much.
Thank you so much for the videos! I’ve learned a great deal watching your videos and really enjoy them. Is there a way you would suggest to add a raised “bead” to either end of a tube made in this fashion? Similar to the raised bead sections in the “complex carbon fiber tube” video. If I try and build an intake tube in this fashion I’d like to help insure that the boots would not blow off the tube.
Hi Jeff, yes, you could do this very simply. Just cut a long thin strip of prepreg and then wrap that round and round as each end of the tube, making the tube considerably thicker in a 'bulge' at either end. This way the tube would still be parallel on the inside (so would release from the mandrel) but you'd get the bead detail you want.
Nice to see you back guys!
Thanks Alexey, we'll try to keep right up with our tutorial releases.
Best composites channel! Congrats.
Thank you for the really kind feedback!
Great stuff, are you guys also planning on a how to on making proper strong inserts in carbon structures? I'm quite worried about using aluminium threaded inserts inside carbon on structural parts. Would love to get to know a bit more about that and how to do it proper.
Great suggestion! Certainly something we will look at for the future.
This would be a great metarial to make a pair of crutches - light and strong.
Yes, for sure. In fact I would be surprised if there weren't carbon fibre crutches on the market, somewhere.
price probably isn't worth it, also considering aluminium ones are pretty light
There ought to be a sport out there that involves crutches.
@@rootbeer666 ain't that skiing?
And they always get stolen by the patients... lol @@seannz100
These are the best educational videos! 🔥🔥🔥👍
Thank you, it's great that you think so!
What an awesome video!
I’d wrap myself in carbon fibre if I could!
Great stuff! 👍🏿👍🏿👍🏿
Good plan. Maybe go for a lower temperature cure though?
I’m gonna use this make a full carbon cold side for turbo setups😁
For the intake part that's a great idea, but I would not recommend to proceed past the compressor. Dimensions for the compressor housing need to be very precisely milled for it to work, and that takes a whole different level of manufacturing experience to achive. Like including thermal expansion rates, the mechanical deflection of the compressor blades at full speed versus low speeds, the whole 9 yards.
Nice!
Would love to see a video of how to attach metal to the CF tubes to help build frames or frame reinforcements, like a strut tower brace.
An ultimate video would be how to create a CF antiroll bar, like the Porsche 911 GT2 RS uses............ :-D
OK, thanks for the comments. We do plan to do a video on fittings and fasteners for making carbon fibre assemblies, we could cover some of the things you're talking about in that.
Easy Composites Ltd showing us how to make a 90 deg bent tube would be nice also.
How well does this pre prefer hold upto heat?
@@easycompositestv I would love to know as well. I'm thinking of a homemade carbon bike with metal lugs.
Very inspiring video! Sparked so many ideas
Amazing vid ! Thx for sharing information and ur knowledge
Happy to help!
Seeing that fresh carbon fiber break just hurt my feelings
It got me excited about how strong this material can be. haha
@@one10RC That too lol
Totally!
What video covers making that tube with the kink in it? Can't recall seeing it. I'd imagine a similar process to the intake manifold you made though.
Ahh, well, what we've done there is mention the 'other' tube video that goes with this one. We've already filmed it (which is how we had the video we needed for that shot!) but we haven't edited it down yet. We plan on publishing it next week. Once they're both up it will make a bit more sense.
@@easycompositestv fantastic thanks for getting back to me! I can't wait as I feel it's very relevant for the projects I've got going on :D
@@GoldenSlothRacing I'm glad you asked this. I've watched every one of their videos, and was wondering the same thing. Looking forward to the next video.
Can’t wait for that one I’ve always wanted to try making different tubes from carbon
I tried different one off methods but turned out crap.
Nice video as always. When I did some tubes for my car I wrapped some extra tows around the ends to make beads, kinda like your step to pull it off if necessary. This way theres much less chance of a coupler popping off. My application was for car intake tubes that see boost pressure.
Yep, nice tip and nice way to get a small, neat step on the end of your tubes. Totally makes sense.
Hey Man, I was exactly thinking about to make Boostpipes for my Hillclimb Porsche 944. It runs in Racemod nearly 4 Bar (something around 58psi). Son now my maybe dumb questions: Can they handle that? I mean it is mechanically strong of course, but air pressure? would really appreciate your answer. Stay safe out there!
Best carbon fibre video's out there! 👍
Wow, thanks Andrew, we try out best :)
@@easycompositestv you succeed! I will be after the kit to make the carbon fibre wings for my a5! Is that the same kit you used for the bonnet?
@@andrew19682008 Yes, the process would be much the same albeit you may not need the inner moulding as we did with the bonnet.
Slight overlap, would that be 5mm or 10mm? For additional strength could more layers help? Rotational strength? You make it look easy. Thanx
The overlap is only necessary to hold the fabrics together during the rolling process, so in this case the overlap was actually very small at around 3mm.
@@easycompositestv with the 5 total wraps around the mandrel, what wall thickness does this equate to after baking?
@@sandman70131 The finished tube had a wall thickness of 1.7mm.
Could you make a carbon tube with a wet lay or infused process instead of prepreg?
You could certainly wet lay in a very similar way to the repair done here and also similarly to a tube repair as seen in our Fishing Pole Repair Video. Infusion would be much harder in a practical sense for smaller tube sizes, although for bigger sizes it may work using a tubular bagging film and extra care to ensure the resin is evenly distributed all around the tube.
You can also make your own prepreg by doing a wet layup on flat carbon and then freezing it. Then when you are ready to make your tubing, just let the home made prepreg thaw just a bit and roll it on just like factory prepreg. It's much less messy that way and the carbon tends not to slip as much during application.
Hi Great Video! thanks for sharing...
1. f you had used the same weave of the one used on the ends for the destructive test would it have been stronger?
2 If you doubled the layer would the strength double? (is it proportional?)
3.If you would have machined rolled more tightly would it be stronger?
4. Would vacuum molding make the tube stronger during the curing than shrink wrap?
Incredible videos as always!!
Glad you like them!
Except the oven step, the rest is the same process of making a joint!
You made me fall off my chair. Bravo
Well, one gets baked, the other does the baking...
Happy 420!
me watching the skinny tube : why the hell would someone want carbon fiber tubes, looks ridiculously feeble, 10seconds later the guy steps on, no deformation, not even one millimeter, put on the press, 600kg required to break it, not even a directional reinforcement was used. wow jaws dropped.
now i believe in carbon fiber.
Very nice project! Thanks for share this precious information
Our pleasure, you're very welcome.
Great tutorial. Thank you.
Thanks Chris, glad you enjoyed it!
His hair stands up at the back exactly like mine
I would like to know, how much the carbon fiber weights per squaremeter.
Well, I think you’d also want to know the thickness too then! 1280g per m2 at 1mm thickness (or 1280kg/m3)
That depends on the specific gravity of where it is being measured. It will weigh more on earth than on mars. Hope that helps.
That changes depends on the amount of epoxy
Depends on the fiber, fabric construction, resin content percentage
Excellent stuff, Thanks.
Thanks Cameron, glad you enjoyed it
Thanks a lot for sharing knowledge.
Huge respect for you..
That's what we love to do.
I have no idea what's going on nor how I could find this useful. But hmmm... Interesting video yes
How does this “homemade” tube compare to its off-the-shelf counterpart in terms of tolerances and resistance? (I'm talking about a tube with the same layup configuration and diameters)
Pretty similar Daniel because - although this is 'home made' as you say, the materials and manufacturing process are actually so similar. Maybe if we get chance we'll compare a tube made in this exact way with a matching tube from our stock range and put them both on the test machine. I'll wager that they'll be within a few percent.
@@easycompositestv Thank you for your answer! That would definitely make an interesting video
@@easycompositestv And what about price performance. Equipment non-considered, should we expect a price benefit for building tubes vs purchase? Or is it added flexibility in design? ... or both?
Where are these tubes strongest? In the video we tested the tube horizontally, is the tube inappropriate for a vertical application?
That is clearly not homemade
@@MM-24 China is always cheaper but the tolerances are usually terrible. You can get a free oven from Craigslist that works just as well as the fancy one he has. All you need to do is get it to temperature and have room to get in the oven. Anyone ,including kids, can make this by watching the video. The tube is the strongest the same way as any tube. Obviously, long thin things are always stronger vertically. There's no reason to not buy it other than pride in making it yourself. You are either a builder or you're not.
ahhhh so thats how those tubes are made! cheers!
I love your tutorial please make more🙏
The interesting thing is not so much carbon fiber wich is strong, but the alternatives. Glass fiber, sandwich with carbon and glass fiber etc. For hobbyists this mean you can make things strong, if you have poor economy by mixing materials
There is a benefit of using glass instead of carbon in certain tension applications where a little flex or shock absorbsion is desirable. Even carbon fiber aircraft such as sailplanes often use special high strength fiberglass in the wing spars instead of carbon.
I would like to explore laminating carbon with more abrasion resistant fibers such as aramid and uhdpe
how many layers of carbon fabric were in this tube?
I need some carbon shovel & broom handles...
Expensive Handles!
Its really a useful and informative video. Thanks
Thank you Khalid
Wow, that is Amazing !
Thank you Mattias, Cheers!
made a world of difference when i switched to a carbon fiber cane...
Im thinking about making a walking/hiking stick. What diameter is yours and what length
@@conniestevenson226 - i didn’t make mine, got it from a company called carbon canes... it’s 3/4” diameter and cane length? like 3’ or so... has flames coming up from the bottom ;¬)
@@grendelum sounds awesome looking. I would think 5 feet would be perfect for what i need. Im looking to use a 28mm kevlar carbon hybrid shaft
@9:14 it has officially been "Defromed" lol
Excellent video, thanks!
Thank you, glad you liked it.
These vids are always incredible. You make it look so darn easy... lol. Though some of the processes I have been able to reproduce!
Hi Cory! Glad you enjoy the video, with practice you'll certainly be able to reproduce most of the processes :)
For the stress tests I would recommend converting it also into Momentum, since it is quite some difference putting 700kg on a 0.30m long tube or a 1m tube or check if it sustains the same if converted to momentum, which will be more accurate :)
The test was purely for demonstration purposes rather than a precise test.
I legit dunno why this is on my recommendation
Super professional human ❤️
Haha, thank you very much!
The best teacher
Thanks Paulina, that's very kind.
I wish i can handle that amount of stress too :/
Don't underestimate yourself, you're a carbon based lifeform.. you'll get through it.. 👍😁
If only people who were interested in submarines saw this video.
Great video! Thanks for sharing it
You're welcome Marco, thanks for watching!
beatifull video , congrats !!
When I saw stress in kg.... 🙈 damn cant un see
Lol
Actually the machine outputs the force it applies versus the displacement of the head (deflection in this case). So kg is fine. The internal stresses can be estimated by considering the dimensions of the tube and the external load applied.
this is so CooL , keep making videos !
Thanks Freddy, we will.
Great video amazing technology and what it can do for you thanks thanks a lot
Our pleasure, glad you like it!
Merci à vous pour cette magnifique vidéo
C'est notre plaisir, merci d'avoir regardé Jean
Always great videos thank you :) I wish also a video for how to make a bladder!!
That's certainly a video we'll be making in the future Richard.
Great video as usual!
Thank you, we appreciate it.
Love these video's!
Thanks Remko, we love making them.
perfect!!! material
Thanks for this helpful video.
Glad you enjoyed Pablo!
amazingly surprisingly strong - thanks for the test - read my mind :)
Great video.
Nice video, well explained without big egos for a change.
If worst comes to worst, remember that common swimming pool acid will dissolve the aluminium tube away in a minute without affecting the CF at all.
A professional fiberglass friend who makes fiberglass tubes, uses cardboard tubes, then just throws them in water overnight.
Interesting comment Mark; it wouldn’t be possible to use cardboard as a mandrel for a prepreg tube like this of course (the process relies on thermal expansion of the mandrel) but it’s a novel way of making a mastic fibreglass tube.
I will probably never make anything from carbon fiber yet I watch video after video from you guys. Love from Texas.
