Carbon fiber has much higher potential, but the fibers in this axle are just in the axial direction. If there were fibers going diagonally around the center axis, the torque would be much higher. But due to the shape of these axles it might not be practically possible. If you could somehow do a pull test, the carbon fiber axle might be stronger than the steel one. But for torque, the carbon fiber axle is probably not much stronger than the resin used to reinforce the fibers.

[@hashbrown777]

Yeah axles are not the appropriate application for carbon fibre. Idk who thought to make them other than selling it to people who think it's a magic buzzword

[@magnemoe1]

Also the size, for something like an car's drive shaft carbon fiber make sense, you can use many layers in different directions and an steel drive shaft is heavy.

[@ABaumstumpf]

@@hashbrown777 Nah, the carbon-fibre axles are GREAT for when you need a stiffer longer connection. Lego them self sometimes use long axles to reinforce things like ship masts and there the normal axles are just not good enough and the carbonfibre fits the bill.

[@hashbrown777]

@@ABaumstumpf hm, if you're not using them AS axles then maybe, but fibre's strength is in tensile, not deflection, and you might find that using pure binder, whatever resin it is holding the fibres, will be just as strong over lego's stock plastic for holding masts without any carbon over the distances these axles are in length..

[@GTLugo]

I'm not a material engineer, but don't you all forget now that the primary benefit to carbon fiber is not necessarily just the strength, it's the strength-to-weight ratio. It's still a good option for when you need stiff, but lightweight rods, such as in aerospace applications. Tom Stanton has used them a couple times for his lightweight airplanes to go with his compressed air engines.

if you order a cheap drill bit set off of temu or wish, for hobbyist purposes, they most likely are preformed through torsion, as shown here, afterwards heat treated and just have been grinding the two cutting edges - if you on the other hand order either coated high speed steel(hss) or carbid drills from a reputable manufacturer those have grooves which have been produced on a cylindrical grinding machine

The steel insertion test is what happens if you forget to chamfer your edges after milling. It had edges at the end that were still sharp, and with a few seconds with a file or abrasive could probably be considerably improved.

[@dazley8021]

Would make them much less affordable tho... and they arent cheap as is.

[@SkigBiggler]

@@dazley8021If they’re expensive then most of that cost is simply mark-up because it’s a niche market. Looking at the steel axles, it looks like the manufacturer bought steel rod in the correct diameter, then used an end mill to cut the grooves. If it was done by hand the cost might be reasonable, but it’s almost certainly done on a CNC, where you could make a change in tooling to an appropriate rounded-edge end mill and get the correct profile without much extra work, making it easier to get parts onto the axle. A nice surface finish might be achieved by putting the axles in a vibratory tumbler.

[@dazley8021]

@@SkigBiggler extruding them with a set of dies that progressively cut it into a cross axle would be much cheaper i bet

[@SkigBiggler]

@@dazley8021 Initial investment in steel extrusion equipment and the dies would be quite expensive. If you already had the equipment or had someone nearby who could do it for a reasonable price, it’d be a better option. The aluminium axle was clearly extruded, but I think the equipment for that is a lot easier to get and cheaper, cause aluminium extrusions are pretty common, and operate at lower temperatures. Using a CNC setup would be a cheaper investment if the axles aren’t a huge seller, cause you can use it to make all sorts of small parts. If you were really mass producing at a huge scale, extrusion would definitely be the way to go, long term costs would be a lot less I think.

[@timplett1]

The edges need chamfering all along the shaft too. You could actually hear a bit of a scraping sound in the sound test which is almost certainly those sharp corners slightly scraping the plastic. This likely hurt it in the friction test as well.

Love the experiments! Very thorough job testing all the aspects of each material. I noticed especially the difference in cross-sectional area between the aluminum and steel axles. The aluminum has very rounded edges while the steel has very sharp edges. Id imagine this probably contributed significantly to the insertion tests. I'm curious if you could do one additional test and report back? (you definitely don't have to, just curious) Use a set of calipers to measure the maximum cross-sectional width and see if there is a difference between the aluminum and steel axle due to the chamfers. Clamp down on the axle at 45deg(where the cross section width would be the smallest) and rotate the axle in the calipers to 90deg. I'm curious if the chamfers of the edges make a significant difference in its maximum cross-sectional width?

[@BrickExperimentChannel]

Well, I'm curious too. :) These numbers I got with a caliper. Hopefully my eyes saw them correctly. maximum diameter: Lego 4.7 mm carbon fiber 4.6 mm aluminium 4.6 mm steel 4.7 mm minimum diameter (axle 45deg): Lego 4.4 mm carbon fiber 4.2 mm aluminium 4.2 mm steel 4.4 mm Looks like the steel axle is thicker and also sharper in the chamfers, compared to aluminium.

[@BrickExperimentChannel]

Good question. I just let the motor run until it doesn't speed up anymore, which I could tell from the sound. Before testing I verified with a laser tachometer that the motor runs at 330 rpm while rotating the plate, both with a plastic axle and a steel axle. The no-load speed of the motor is also 330 rpm, so the friction and air resistance are negligible compared to the power of the motor. The biggest source of error is in my opinion the variance in the motor top speed. It varies maybe 5 or 10 rpm up or down.

It likely doesnt matter because the ranking was the same at the higher load, but having a more consistent release in the car friction test would increase the accuracy and precision of the results. Ideally a mechanical release that doesnt impart any forward or backward momentum would be ideal, such as raising a boom gate with a programmed motor or similarly retracting a bump into the ground. Same with the noise test. Using the rpm method from before would have been better.
