Carbon Fibre Tubes - Everything You Need to Know 

You guys deserve all the success you get; these videos are some of the best marketing I've ever seen (and I've been in the business for decades). You're not simply selling a product. You're putting genuine effort into releasing detailed, helpful, well written, and well presented content that's available to everybody, not just your customers. You continue to demonstrate a sincere commitment to helping people improve themselves and their projects, and very few companies can say that. I know that there's a hell of a lot of work that goes into these videos, but to my mind, it's the perfect marketing tool for your particular product.

I don’t even work in composites but these videos are always entertaining

These videos are the gold standard (prepreg roll-wrapped gold) for consumer-oriented technical information. Thanks and Merry Christmas to Paul and the Easy Composites team.

I COULDNT FIND THIS INFORMATION ANYWHERE ELSE . Thank you!

Slight correction, stainless steel has the same Young's modulus as mild steel. In fact, almost all types of steel have Young's moduli of 200±10 GPa. Heat treatment does not change this either.

Another great video with test data and excellent explanations on everything. Happy Holidays Easy Composites and Everyone in the comments!

Smashing production...clear, concise and informative.. Thanks

I love the fact that you take selling your product to a whole new level by demonstrating improving the value of the materials. I would like to see more in depth information on fiberglass and Kevlar and the main differences between the polyester resins such as General use and mold making and if you just happen to have some extra time to go over the real differences about epoxies and polyester types of resins that can be used and why. Also can you get a us-based office.

I have been binging these videos for days. My confidence in doing more complex geometry has skyrocketed. I was heartbroken to find you don't have a US storefront though. I hope it's coming.

You could redo these tests while using an 8mm bar as filler in each end to give a solid grip on each tube reducing the stress risers at the collet. This would focus the test to just the tube section between each collet and provide sufficient grip without crushing

Another superb presentation, with hours of work to put it all together. Thank you!

Sweet!!! It's always a great pleasure to learn from Easy Composites!

Love your videos, as I always learn so much in a matter of minutes. A1 production and editing! 🇦🇺🤜🏼🤛🏼😎🍀🎅🏻

I get happy everytime I see this guy - I know I'm about to learn somethin'

I watched it out of curiosity... Great material 🙂👍 I'm sharing it🎬📺

apart from the result differences of metal and composites, you have hidden potential of an excellent teacher. teaching is not about having a PhD degree, it is all about making the things comprehendible for the students ! Bravo 👍👍👍

Great video. Fantastic summary.

Another super interesting presentation - good work 👍

awesome) very useful. Thank you

fabulous! Again blown away about the thorough informations and tidbits like the reverse engineering.

Awesome video, Thanx for sharing ❤❤❤ happy holidays 🎉

Excellent production guys! Informative and succinct whilst covering all of the common concepts.

Always a great day when Easy Composites has a new video out.

Incredibly informative and I have to say the best channel for composites. I’d love to see a video on recreating plastic tabs for say mirror caps or other clip in components. Everything I’ve learned I’ve learned here and gave me to confidence to put into practice. Keep up the amazing videos

We need some epoxy generational innovation/discovery. Great vidy : ) Merry Christmas

Looks like Christmas came a couple of days early! Thanks for another great video!

Brillant in all aspects, as always

What a great analysis, thank you!

Best composite material channel on RU-vid 😃excellent content again, thank you very much sir

No carbon fibers were harmed in this video. 🤣 Great video! Thanks for sharing.

This video is outstanding. From the presenting to the production, it far exceeded my expectations! Glad to be a customer of yours.

Great video as always! Would love to go into details on how to bond carbon fibre tubes to metal parts like you said in the last part.

That small diameter pultrusion tube is pretty impressive. Cool they can go that small

damn, really good video! I'll keep that in mind if I ever need cf tubes

Thank you for also comparing performance by weight.

Very interesting!!Please make a video on bonding, thank you.

Great to hear @ 14:16 that my woven finish carbon fibre kite frame :) out-performs aluminium at less weight.

Hi guys, I love all of your tutorials but I would love to see you do a carbon fibre motorcycle fuel tank. I'm sure many people would love to attempt this for themselves

Hi, great video. Perhaps you could give the dimensions of the double bend rig so those of us interested can work out the bending moments and Si units. Something on joining tubes (eg how much fibre wrapping etc) would be nice.

You are the best!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

excellent!

When selecting tubing for an application; choosing larger diameter thinner wall or smaller dia and thicker wall is always a challenge on which one to choose or which way to go.

It's funny I was trying to decide which tubing type I was going use to replace the arms on my delta 3d printer just a couple weeks ago. This is by far the best comparison I've seen, just a couple weeks late. I ended up going with roll wrapped tubing and decided to use threaded inserts with epoxy to attach to magnetic ball joint sockets.

Could you go into constructing with and joining carbon tubes? I would like to know since joint failure seemed to be a theme in the tests

Very cool to watch. I was waiting for a mention of fishing rods. Carbon fibre has revolutionised them. Using a carbon fibre (I assume they’re carbon fibre) rods is a complete shock to the system, how can this ultra stiff rod cast like my old fibre glass rod. It doesn’t take long to get used to casting and loading up the rod with energy to let it fire my lure way further than the old glass rod. Lightweight and strong, stiff too but easy to cast long distances.

seeing these results makes the carbon fiber driveshafts they put in these 5000hp cars far more impressive than they already were.

⭐⭐⭐⭐⭐ video. Thank you.

I found it really interesting how weak carbon fiber is in torsion. Great video!

Nice.

This video was really helpful for an upcoming project. In the project there will be a joystick handle attached halfway down the tube and an end plate at the end. The intention is to have aluminium pieces machined to join the joystick and to mate with the end of tube. I would be interested to know the best methods of joining aluminium to carbon fibre components.

Hi, it would be great if there was a video about how we can make larger and more complex products, such as car bumpers, from carbon fiber. I'm sure it would be useful to many people.

I’d really like to try making something out of carbon fibre Once I have more space I’ll definitely give it a go

11:11 the use-case carbon tubes waited for

Bound aluminium with CF is very interesting theme, hope you would reveal best practices in that matter in next videos

Hello Thank you for the valuable information you provided. I have a question For example, can we use a product made of carbon fiber as a mold? Also, what do you think is the most appropriate method in mass production to produce a carbon fiber product?

It is interesting to see how the elastic modulus behaves at small deformations. In theory, with different types of weaving, different fibers should “switch on” at different moments of deformation. I saw an emphasis on this in the discussion topic of bicycle frames. At low loads they are “soft” and comfortable, and at large loads they are harder so as not to steal the rider’s energy. At the same time, when used in delta 3d printers, we need maximum rigidity at low loads.

I am interested in piano tuning levers. The tubes are about 300mm long. Tensile, compression, and torsion is not important but bending and hoop strength are key. Very high hoop strength and very little bending. Most I see are roll/wrap about 18mm to 22mm OD but I have no idea what ID they have - probably 16mm and 20mm respectively. How does the hoop strength increase and bending descrese if I used instead of 18mm x 16mm I used smaller diameter but thicker wall, say, 16mm x 12mm. Do you have a video where you compare tube wall thickness - same OD but different ID's for hoop strength and bending comparison? Also, I know UHM carbon fiber roll/wrap has less bend but it is brittle and will break under very heavy bending (but still maybe ok for piano tuning lever use). My idea is to allow an optional Stainless Steel rod to be inserted inside the tube to add more weight and some strength. Some people like the lighter weight of carbon fiber levers, but some prefer a bit more weight to them because heavier levers are bit eaiser to home in on the tuning pin when your arms are used to heavier levers. Is there a chart for all this?

do more videos, you are awesome!!

Hi, thank you for this informative video ! How much better would a Pull Winded or Braided tube would perform in torsion compared to a Roll Wrapped ? Regards

Excellent information as usual! Any thoughts on type of cloth and layup style to create a torsion bar? Porsche have upgraded CF anti-roll bars for the GT2RS and for 1 of my cars, reducing weight at the very front of the car (reducing the ARB's polar moment of inertia within the car) with a CF anti-roll bar, certainly the torsion bar section, would be a nice improvement.

Is there a specific epoxy resin for making a carbon fiber part ,,or you can also use table epoxy to make a carbon fiber

Hello. I want to ask you if it is okay to make a hanglider with carbon fiber frame.

Wonderfully informative video. I wonder if you could do a video on the stresses of sleeved (telescopic) tubes. I have read that one need an overlap of between one fifth and one quarter of the length of the unsupported arm. So if the unsupported arm is 80 cm one needs an overlap of between 16 and 20 cm. Is that correct?

Hey Paul could you cover a video on how those fancy 2meter / 3meter carbon fiber sail planes. How do they get it to weight almost nothing?

great content. how to securely glue a carbon tube with an aluminum sleeve?

Great video , if you increase the diameter say from 10mm tube to say 20mm tube , does the strength double as rough guide ?

The small tubes are really nice, any chance to do a strength test on some of those?

It'd be great to do something similar, but comparing tubes to solid rods of CF. and then again, but box vs round tubes.

I would have liked more information relative to the wall thickness of the materials used in the demonstration How would a 2mm wall thickness compare to 1mm in carbon fibre. I'm in the process of building a yacht steering wheel and I have chosen the tube with the heaviest wall thickness for the spokes not knowing what pressures the spokes will have to sustain. It is a bit of a suck it and see project.

Im curious if its worth using composites in a rust repair? instead of using thin steel to replace a gusset, use carbonfibre which wont rust again, my car has rust sills for example

What would be the best way to bond a CF tube to a CF plate? (Application: I need some stand-offs for an engine cover)

Can you bend these tube's into a custom shape or how would you make these tube's with a 7mm OD and a bunch of curve like bike seat rails?

Hey guys do you have some details about carbon fiber cones (taped tubes for fishing rods)?

C'est une étude très intéressante car souvent on hésite avec les différentes techniques si on peut les utiliser à la maison .....par contre tu as une trace noire sur la joue 😂😂merci encore pour le partage.

As noted in other comments, an excellent video. If you could just give us the distance between the supports on that test machine and the outside and inside diameters of the roll wrapped test tube, I could work out a section modulus, a bending moment and, essentially, a stress limit. I have the root bending moment on my model aircraft wing but I need that stress limit to make the best tube size selection (retired aircraft stress engineer). I'll post the calculation here.

Can I use Carbon Fibre Tubes or Squares as Struts in larger Geodesic Domes to take advantage of the low weight...

I see a lot of CF videos where the product comes out sort of floppy, and I thought CF was supposed to be really rigid. What's the best way to get that strength out of the CF; is it in the wetting out process, in the way you arrange the weaves, or simply lots of layers? Or perhaps something I'm not aware of?

Hi, what would be a more suitable grip method for the composites?

Is it possible to build a carbon fiber tube chassis for a formula racecar using aluminum nodes?

I need carbon fiber tubes for a 3D printer. I am using plastic bushings for Igus. That is the same setup as Bambu Labs are using in their current printers. The issue is finding straight tubes with the accurate dimensions. It is not that carbon fiber does not work with bushings, as they do with plastic ones from for example Igus. Also, I would prefer a bit bigger diameter if possible. Preferably like 12mm maybe 16mm. I guess 8 or 10mm could work, but given the stress they are put under, 12mm seems prudent. Do you guys have anything I could use? Are yours straight? Is the OD accurate? I guess we are looking at something stranded?

Tutorial kayak pedal fishing bro, Di tunggu videonya

Really interesting video. What was the diameter of the tubes you were testing?

Is it possible to drill a 5,2 mm hole on the upper and lower part of a carbonfiber roadbike fork in order to line up the braking cable internally? Or is this to high of a risk as you dont know how much this weakens the fork itself? Problem is you have clamping forces from the stem and also expanding forces from the expander?

What I need is a way to join small tunes to larger ones like a T joiner. I need to be able to have one larger diameter tube then have smaller diameter ones crossed over running above or below. I want to construct Yagi antenna booms then wrap them in braid wire for the conductivity. Or is it possible to have the braid in the tube? I may email you guys soon. Thanks. Shane VK1NME.

any reason why carbon fibers are generally treated as if they're all the same in your videos? in reality some carbon fibers are 4-5 times stiffer than others and tensile strengths also vary by a factor of at least 3-4. love the videos and would like to see something on that topic as well.

What is the best way to thread and secure a rolled CF tube? roughly 36mm, that will experience moderate loads perpendicular to the tube. It seems the failure rates of your test subjects were around the mounts.

Hello, Sir. I have a question. Before creating carbon fiber composite parts for cars, I'd like to know, based on your experience, which machines you consider better - CNC router machinery or 3D printers? And why

What kind of aluminum are you using for these tests?

Wanted to make a 45” L x 31”W 1/2” thick table top only made from carbon fiber what would be the best way to make it and should I? I don’t want to just simply wrap carbon fiber over a wood slab.

I was thinking about aluminum carbon fiber laminated layer comes out with high tensile strength, but on pipe ... why you didn't demonstrate how much bar psi pressure inside it's tube could barely resist?

What happened to Paul's grill?

Could you please explain why carbon fibre drive shafts are sometimes used to replace steel ones. The very low torsional performance figures in your tests would indicate it's better to stay with metal.

Having fatigue failure tests would have been awesome

How do you tread them for high pressure seals

Hi there, hello. I'm having trouble finding out information from Google. IDK if it's a bad idea and I don't want to waste my time. I'm modeling a mold for a carrying case im building. I want to add a spot where I can fit a nut so that after the carbon fiber cures i will be able to screw in a hinge without drilling. Is this a bad idea?

You should make a video on making a tube bend (45°, 90°). No such thing exists so I made my own but im surprised its not a common item.

Gooday can u manufacture solid 7mm rods.

What about internal pressure? Say you got 20 bars or more on inside.

I am surprised the CF performed so poorly in the torsion test compared to the metals. CF driveshafts are used in high end sports cars for their ability to take on crazy amounts of torque compared to metal driveshafts. Are they different than what was shown in this video? can somebody help me understand?

what about weaving them like a kellums grip?
