摘　　要：采用DSC法研究了FUCHEM 879环氧乙烯基酯树脂体系的固化过程,分析升温速率对固化体系DSC曲线的影响,确定了该固化体系的反应动力学方程;采用外推法从理论上得到树脂体系的凝胶温度、固化温度和后固化温度等固化工艺参数,并由实验得到了优化的固化工艺。The curing reaction of Epoxy Vinyl Ester Resin was studied by using of DSC. Effects of rate of temperature increasing on the characteristics of DSC curves were investigated. The curing reaction equation of the Epoxy Vinyl Ester Resin was ascertained. Gelling temperature , curing temperature and posttreating temperature were obtained by extrapolating T-βcurves. Based on the theoretical curing temperature, optimum cure processing parameters were attained by means of experiments.
