Composite fibre fabric
Composite fibre fabric
(OP)
Hi,
Does anybody know of a composite fabric that can withstand high temperatures (400F) & be waterproof at the same time?
Since this would be a fabric and needs to be somewhat flexible, what kind of matrix could be used? Is there any matrix that can give flexibility and be waterproof at the same time?
Any help would be appreciated.
Thanks,
Mike

A thermoplastic matrix such as PEI would also do, through that might be a bit stiff.
Depends a bit on what mechanical properties you want and what temperature range you want them over. A thermoplastic like Nylon 66 would be above its Tg at 400 deg F and would be somewhat flexible, but would lack flexibility at lower temperatures.

Its clear to me that I will be using a fiberglass fibre. Between silicon & teflon as the matrix, I think teflon is cheaper, so I will go for teflon.

I want to cover a cup like structure (with 2" OD) which will be under 16000 psi external pressure. I don't think this fabric might be able to hold it looking at its tensile strength properties. But I am not sure how to calculate the shearing load for a composite fabric. Any ideas?
