摘　　要：对3种配方的真空辅助传递模塑(VARTM)工艺用环氧树脂,采用动态升温DSC实验,升温速率分别为5、10和15℃/min,引入Kissinger理论,确定了树脂体系的表观活化能分别为4.32kJ/mol、5.57kJ/mol和3.49kJ/mol;利用外推法,确定了参考固化工艺温度。Curing reaction of three kinds of epoxy resin in VARTM was studied by DSC（Differential Scanning Calorimetry）in this paper. The transforming speed of temperature were 5℃/min, 10/min, 15 ℃/min. The surface active energy was calculated by Kissinger method, 4.32 kJ/mol, 5.57 kJ/mol, 3.49 kJ / mol. The referenced curing processing temperature were calculated by Extrapolation.
