摘　　要：为了优化环氧树脂/聚酰胺(EP/PA)体系的固化工艺,采用非等温DSC(差示扫描量热)法研究了环氧该体系的固化过程,并采用Kissinger方程、Crane方程和T-β外推法计算出该体系固化反应的动力学参数和固化温度。研究结果表明:当m(EP)∶m(PA)=2∶1时,EP/PA体系固化反应的表观活化能为53.67kJ/mol,反应级数为0.894。结合不同升温速率下的特征温度,对环氧树脂的固化条件进行了优化。In order to optimize solidification process parameters of epoxy resin/polyamides （EP/PA） system, the curing process of EP/PA system was investigated by non-isothermal DSC （differential scanning calorimetry） method, and the kinetics parameters and curing temperatures of curing reaction of EP/PA system were calculated by Kissinger equation, Crane equation and T-β extrapolation. The research results showed that the apparent activation energy of curing reaction of EP/PA system was 53. 67 kJ/mol and reaction order was 0. 894,when mass fraction of m（EP） ： m（PA） was 2 ： 1. Furthermore, the curing condition of epoxy resin was optimized according to the characteristic temperature at different heating rates.
