Hmmm...I thought Kevlar had near zero elongation before failure, which ideally should make it a good stiffening component in bending. I know fiberglass will stretch and I'm not sure about CF. I guess I should dig out my engineering books...
Just looking for ways to make some stiff composite structures without breaking the bank...Kevlar cloth is ~1/3 the price of CF cloth. I might just have to buy a yard of it and see how it performs...I was hoping someone here might have tried it before.
