Study on curing kinetics of novolac epoxy/bisphenol A cyanate resin system

Demin Jia

Abstract

Curing process of the blends consisting of different amount of cyanate ester and epoxy resin is studied by means of DSC.Curing kinetic parameters are evaluated and the relationship between the system is investigated.The lowest apparent activation energy values of EP/CE blends with molecular ratio of 2/1 obtained by Ozawa and Kissinger treatment of DSC result equal to 54.86 kJ/mol and 49.05 kJ/mol respectively.The nominal reaction orders are between 1 and 2 by Crane method.
