When I make parts using composite materials and epoxy, I allow the epoxy to cure for three hours then I place it in a hot box of sorts. I take the easy route and wrap an electric heat blanket around the part. This gives me about 120 degree Fahrenheit. I leave it there for about eight hours and I have a nicely cured setup part. I use Aeromarine 300/21 epoxy and they recommend curing at 30 degrees F above the intended temperature use.
I show this an much, much more in my instructional DVD's.
All the best.
