Food for thought:

Elastic modulus + Geometry --> Stiffness/Flexy-ness

Yield/ultimate strength + Geometry --> Strength/Permanently bent

Fracture toughness + Defects + Geometry --> Fracture (what we saw in the video)

Of course in CFRP the fibre orientation plays a large role in modulus, strength, and fracture toughness.


All I'm trying to get across is that I could make you a $5 handlebar made from glass that is much stiffer than any CFRP handlebar you can buy.
