I'm looking to make a part using Divinycell and prepreg, but I'm concerned with the thermal expansion of the foam causing poor bonding or internal stresses after cure. Does anyone have experience with using elevated temperature cure and a foam core such as Divinycell? I'm going to try to find a low temperature prepreg, but at best it would likely be 80C which is pushing the recommended processing temp on the data sheet which is 90C.
