I am looking for a vendor or supplier that has a prepreg carbon fiber, Kevlar and fiberglass that has a cure of 180F or lower with a cure time less than 1 hour. Anyone know of such a place? Thanks for your help!
This 120C cure for one hour , or 248F is the closest to what you seek that I know of .

There are other fast cure prepregs out there but many are at much higher cure temps .HTH
180f cure prepregs mostly 8 hour minimum cure cycles. One hour cure is possible but probably has a 12 hour outlife, 24 tops…
Cytec has the LTM (low temp moulding) series. They have an initial cure at I believe 122F. However there after they must go in to a free standing post cure at higher temp. There are also other companies such as Gurit, Amber composites, and a hand full of other companies that have similar products.
even with 180F cure, you’d probably need a higher temp post cure. I"ve been curing my stuff at 110C for 1+ hours and they come out great. I"m using cytec mtm. I had some other material that was 180F cure, that only needed like an hour or less if you went to 250ish. But sadly, the material I have is pretty stale.
