doi:10.19491/j.issn.1001-9278.2011.12.012

Abstract

Abstract: The cure kinetics of epoxy resin (AG-80 and TDE-85) modified bismaleimide/cyanate (BMI/CE) system was investigated at different heating rate, using non-isothermal differential scanning calorimetry (DSC). The curing kinetics parameters of the system were obtained by Kissinger, Ozawa equation, and Crane's theory. For epoxy resin (AG-80) modified system, the average activation energy was 81.55kJ/mol, and the reaction order was 0.93. For epoxy resin (TDE-85) modified system, the average activation energy was 69.25kJ/mol, the reaction order was 0.92.Compared to epoxy resin (AG-80) modified system, the results indicated that the addition of epoxy resin (TDE-85) could lower the activation energy of the modified system and the curing reaction could occur at a relative low temperature.
