采用差示扫描量热法（DSC）对树脂传递模塑（Resin Transfer Molding,简称RTM）工艺应用双酚A型乙烯基酯树脂体系的固化工艺进行研究,分析不同升温速率对固化体系的DSC曲线的影响,并利用Kissinger方程、Crane经验方程等固化动力学方程,确定该固化体系的反应动力学方程t=1-[1-5 584.65exp（-4 352.90/T）t]6.67,采用温度-升温速率（T-β）外推法从理论上得到体系的凝胶温度、固化温度和后固化温度等固化工艺参数为61.66,74.55,95.49℃。在实际应用中,由于内部反应热存在,适当降低使用温度。固化动力学方程及固化工艺参数对树脂传递模塑（RTM）工艺有重要意义。

英文摘要：

The cure technology of bisphenol A type vinyl ester resin system applying to RTM was studied by differential scanning calorimetry（ DSC）. The curing reaction equation of the resin system was ascertained by Kissinger and Crane equations. The equation was t = 1- [1- 5 584. 65exp（- 4 352. 90 / T） t]6. 67. Gelling temperature,curing temperature and post-treating temperature were calculated by extrapolating Ttemperature-Heating rate（ T-β） curves and were 61. 66 ℃,74. 55 ℃,95. 49 ℃,respectively. In practice,due to internal heat of reaction,applicable temperature need to reduce. The curing reaction equation and cure parameters have great significance for Resin Transfer Molding（ RTM） process.
