Not that I know of, not reliably. My experience with curing 2080 under heat is that it sometimes cures in the vacuum taps before it cures in the laminate. The result is vacuum loss and an expensive junked part. Now we're very careful about how we filter the taps and how we apply the heat.Are there systems that heat cure as they exotherm?
That is the general relationship. But don't let yourself be intimidated; we made a perfectly good post-cure oven with stuff from the hardware store and Dollar General. We do a pre-post-cure of the individual parts in the molds to 100 F with heating blankets and quilts from the thrift store, that gets things tough enough to demold. Then once everything is assembled and bonded together, we ramp them in the hot box up to about 170 for four hours, hold there for another three or four, then de-energize the heating elements and let it ramp down overnight. Coupons are showing this is perfectly fine for the properties we're looking for.Just a random thought....but it seems perhaps higher strength and higher Tg come with a post cure heat treatment......Perhaps the key phrase is "post cure"
That often kind of works. But the ramp rate and temperature distribution are hard to control.One could make the argument that you can post bake your epoxy by merely letting the aircraft sit in the hot sun for x hrs/days.
the sun will bring the core temperature up to over 150-170 degrees very easily.
Post bake cure problems solved.
