Because the tests weren't done to any proper standards, we'd be a bit wary of anyone using the results to derive performance data on the tubes. For example, the 3D printed saddles on the 3-point bend test compress quite a bit. Whilst it's still a fair comparison between the different tubes, this would cause inaccurate data on the stiffness of the tubes per-se. Noted on some more joining information; this is something we'll have a think about : )

That could be a topic for a future video yes. It's generally a case of bonding inserts into, or onto, the carbon fibre tube and then linking the inserts. Composite joining sections are an option but are very expensive (due to the huge complexity involved in making them). As rtz points out, you can also bond smaller or larger tubes inside or outside of the main tube to sleeve or ferrule them where you need additional strength.

Around 6 minutes, it was claimed that stainless steel is stiffer than normal steel. That is incorrect. In fact, the modulus of stainless is very slightly lower. Surprisingly, no matter what steel alloy, the modulus's are all very similar. What is more interesting, if you compare equal weights of metals, their stiffness is remarkably similar.
@robkennedy65649 ай бұрын
I came here to say this! I think this common misconception perhaps comes from most people's experience that typical austenitic (304/316) grades of stainless steel have higher hardness than most low carbon steels - e.g. if trying to drill them (more so as stainless is more susceptible to work hardening). But of course hardness and modulus are not the same thing...

Good comments both of you and yes, this is a legitimate error in this video. We know that the Young's modulus of stainless is the same as mild steel, but somehow this sneaked through in mis-reading of the script.

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?
@easycompositestv7 ай бұрын
Hi Paul, We don't have any further videos that directly address this, but for a tuning lever at 18-22mm O.D. Even a 1mm wall would be almost impossible to break by hand with a 300mm lever, I could imagine that going thicker with the wall might be needed to eliminate any flex as I would imagine that's important in that application. You could start with a 1mm wall and just add layers to the outside until you have the performance that you need, then you'll know exactly how many layers to use for the second one!

There are many rod manufacturers that use these carbon fibers, but I would bet that less than 1% understand their practical (not theoretical) qualities.

Carbon fibre can be extremely good for making lightweight high-pressure vessels, you'll see a lot of tanks (such as hydrogen tanks) made either from pull-wound carbon fibre, or from aluminium wrapped in carbon fibre. In fact, there's a clip of this process included in this video when we mention pulwinding as another type of tube construction method. In terms of the tubes on test here, the pultrusions and the roll-wrapped, they are both designed for longitudinal stiffness, not to resist internal pressure. With no 'hoop' fibres, the pultrusions would be terrible for internal pressure. The roll-wrapped tubes which do have hoop fibres would fair much better but could be made *much* better by increasing the amount of fibre in the hoop direction.

Are they different than what was shown in this video? can somebody help me understand?

As explained in the video, its all about fibre orientation - especially for a tube such as a driveshaft where the fibres will be specifically aligned to resist twist.

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?
@easycompositestv4 ай бұрын
Unlike a thermoplastic, composites like the tubes can not be heated and bent to to shape. To hold any kind of shape they need to be moulded in this manner, for larger diameter tubes this can be done with a multi part mould and internal vacuum bag however this isn't appropriate for such small diameters. The only option really would be to 3D print a dissolvable core and wrap it with a braided sleeve. Once cured the internal structure can be dissolved from the centre.

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.
@easycompositestv9 ай бұрын
They have the fibre orientation specifically orientated for torsional performance. These stock tubes do not. Compared to homogenous materials, composites are all about fibre directions and direction of loading.

I found it really interesting how weak carbon fiber is in torsion. Great video!
@dekutree649 ай бұрын
Yeah, I always thought the difference in torsional performance between roll wrapped and pultruded tubes was much greater. I wonder how tubes made from woven sleeve would compare?
@teeanahera89499 ай бұрын
This test wasn’t able to show their real properties as the presented often mentioned it was the difficulty in gripping the tubes that caused them to fail early.

Its not something we stock. Many conical tubes can be made by the roll wrapping method.

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
@easycompositestv8 ай бұрын
They are completely different so depends on the specific application.

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?
@easycompositestv9 ай бұрын
I suspect they have the tubes specifically sized and spec'd for their requirements.
@FrodeBergetonNilsen9 ай бұрын
@@easycompositestv probably not that much. They need to be straight and have an accurate OD. Actually there are plenty of people using carbon fiber tubes this way even on youtube. So my question is, do you have fairly straight tubes? As for accurate OD, if I try to buy that of the shelf, does that exists?

Is the carbon fiber UV resistant? Is carbon fiber stronger than E-glass?
@easycompositestv2 ай бұрын
Carbon fibres are completely UV stable (although the resistance of the resin matrix will vary) and have a higher modulus and tensile strength than E-Glass.

Of course 700kg is understood differently than 1.3GPa, these are to different units of measurement, and not comparable in any way XD.
@easycompositestv9 ай бұрын
Well, we've already provided the measurements of the tubes so the cross-section is known. If you know the cross section then you *can* compare the load in kilograms to a force/area unit like pascals. We understand the science, we're just genuinely trying to make this information more meaningful for the majority of people.

Is it possible to build a carbon fiber tube chassis for a formula racecar using aluminum nodes?
@easycompositestv4 ай бұрын
In theory it would be possible yes but it's not really a mechanically efficient way of doing so. A monocoque construction is far more suited to the performance of a composite material due to the way that it can spread the load.

I've gone down quite the rabbit hole over the past few weeks, listening and learning from Paul and the team at Easy Composites through these fantastic, informative videos. As an engineer, these videos naturally peaked my interest from the start. What initially was entertainment for me has quickly evolved into a list of parts I fully intend to start making out of carbon fiber for our business. I'm excited to start experimenting and I look forward to future videos! Thank you a ton for these videos, you've earned a loyal customer! Cheers from Oregon, USA.

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?
@easycompositestv5 ай бұрын
Maybe it's something we can look at in the future. I'd imagine that the roll wrapped tubes would perform pretty well given the fibres running round the circumference would all be in tension. Finding a way to securely block off the ends and have a valve which wouldn't blow out might be a challenge though.

Similarly to the Woven finish roll wrapped as the construction is very similar except for the cosmetic woven outer layer.
