Study on curing process of bismaleimide/cyanate ester resin modified by epoxy resin

Kaichang Kou

Abstract

The curing reaction process of bismaleimide/cyanate ester resin(BMI/CE) modified by AG-80(glycidyl amine type epoxy resin) and TDE-85(alicyclic glycidyl ester type epoxy resin) was investigated by DSC and FT-IR methods,and the kinetics parameters of curing reaction were calculated by Kissinger equation and Crane theory for the modified resin systems.The results showed that the apparent activation energy was 68.11 kJ/mol and reaction order was 0.860(approx 1 level reaction) for curing reaction of modified resin system.The epoxy resin(EP) could promote the curing reaction of CE,and the modified resin system could be completely cured at150 ℃/3 h→180 ℃/2 h.
