What is the lowest temperature composites can go
What is the lowest temperature composites can go
(OP)
I have a Tg temperature of 190 C for a composite after curing. I am told that structural properties are good up to that temperature ( or some amount below it like 30C) How do you know if a composite is good for lower temperatures, for instance an e-glass or similar at -45C? Thanks

"how do you know?" run a test or two or more ...
Composites are used on aircraft at ~ -65F all the time.
Composites are used on spacecraft at much lower temperatures

Confess I don't know about low temp props of glass, but I'd be very surprised if -45°C was a problem with basic laminate properties; should watch CTE vs. other materials, of course. CTE E-glass/epoxy 10 – 16 µe/K.
