摘　　要：采用差示扫描量热(DSC)法和红外光谱(FT-IR)法对缩水甘油胺型环氧树脂(AG-80)与脂环族缩水甘油酯型环氧树脂(TDE-85)共同改性双马来酰亚胺(BMI)/氰酸酯树脂(CE)的固化反应历程进行了研究,并按照Kissinger和Crane法计算出该改性树脂体系固化反应的动力学参数。结果表明:改性树脂体系的固化反应表观活化能为68.11 kJ/mol,固化反应级数为0.860(接近于1级反应);环氧树脂(EP)可促进CE固化,当固化工艺条件为"150℃/3 h→180℃/2 h"时,改性树脂体系可以固化完全。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 at＂150 ℃/3 h→180 ℃/2 h＂.
