Pushrods, rockers, blower rotors , pistons, aswell as carbon ceramic flywheel.
How stiff can a carbon fiber item be made? Thinking pushrods and rockers for big SR cam etc.?

Could you help me take the splinters out of my fingers on disassembly?

Typically the elastic modulus of the carbon compositec is Anywhere between aluminium and steel depending on fibre orientation and percentage that is fiber and percentage epoxy. It varies a lot

Id guess that different epoxies would give a different result? I really know very little about CF.

Yes particularly as a function of temp, also there are different fibers as well.

Ok cool, as said i really know squat about CF, its strong and light thats it really, none of the techy stuff.
So its definitely feasible to use as a piston?
Could we see full CF rotating kits one day, possibly blocks, heads etc?

I think what everyone here is looking at is another Silverback carb.

No this just spurred me to think more about CF possible uses and seek some info.

Its mature technology. If it was feasible F1 would have made those components long ago and their use would be trickling down. Meanwhile incremental improvements in traditional materials continues.

I suspect if rules allowed it they would have

I see merit in both of those answers!

At 18K a set, I suspect someone might try and justify the price point.

Awful lot of square corners there for a composite part.... A bit of background research reads like the founder has been a successful entrepreneur in dental technology #-o and as they raise funding they plan to hire or contract the appropriate talent to actually develop specific parts.

That's just an employee. Arthur Warfield is the founder, I thought. Athur Warfield is also the AW in AWA Composites. At least that's how I understood it.

And what about all of those other parts? Silverback carbs, too? The pistons are called a carbon composite. Possibly 3d printed using an additive process? Advancement in 3d printed parts seems to be coming along quite nicely. I came across a company doing carbon something 3d printing a while back.

According to their website, some of their projects include things on the Lockheed Martin F35 Lightning II. If they've got the talents to gain the respect of their peer group in aviation, wouldn't that give them at least 1 leg to stand on and not just automatically assume whatever they produce is no good?

Reading about Lamborghini's upcoming carbon fiber rods, it doesn't seem that far fetched that this place could be using a similar technique to produce a forged composite rod. It(forged composites) does seem to be one of the things they do.
