Carbon Fibre Tubes - Everything You Need to Know

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.

carbon won yeyyy! wanna use un hollow carbon fiber vs aluminum, and see who wins

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

What kind of aluminum are you using for these tests?

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

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

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

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.

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

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.

Nice.

How do you tread them for high pressure seals

The internet is a series of tubes...

You block your dream when you allow your fear to grow bigger than your faith.

what about weaving them like a kellums grip?

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.

The only thing you need to know is this. The inanimate carbon rod, saved Homer Simpson and the space shuttle.

Brillant in all aspects, as always

Great info, but please stop with the hands constantly waving about; it is very distracting.

do more videos, you are awesome!!

would have been amazing if you could have thrown in a 45 -45 roll wrapped tube to even out the torsion game

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.

Now do one on glass fibre?

could you make tubes with carbon fiber braided tubes?

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.

Gooday can u manufacture solid 7mm rods.

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

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

What happened to Paul's grill?

"This is how are the gantry rods of your Bambulab printer actually made"

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.

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

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

awesome) very useful. Thank you

What's the layup? How many 0's, 45's and 90's are you using?

Having fatigue failure tests would have been awesome

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

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

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.

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

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

What about use as a linear rail?

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

Another super interesting presentation - good work 👍

Carbonfiber looks like a cleaning rag 😂

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.

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.
