摘要
Abstract
The cure kinetics of epoxy resin （AG--80 and TDE-85） modified bismaleimide/cyanate ester （BMI/CE） system was investigated at different heating rates, 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. 55 kJ/mol, and the reaction order was 0. 93. For epoxy resin （TDE-85） modified system, the average activation energy was 69.25 kJ/mol, and 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.关键词
