摘　　要：用红外光谱法研究了芳纶抗弹复合材料中改性F-46环氧树脂基体的固化特性,用环氧基团相对浓度的变化速率表征环氧树脂基体的固化反应速率。研究了环氧树脂基体的固化反应速率随固化剂含量、固化反应温度的变化规律;根据固化反应过程中环氧树脂基体的环氧基、酯基和醚基等各活性基团相对浓度的变化情况,探讨了环氧树脂基体的固化反应机理。The effect of curing agent content and curing temperature on the curing rate and the structural change of the epoxy resinmatrix (modified F- 46 epoxy resin) in the aramid fiber reinforced composites were studied by means of infrared spectroscopy. On the basic of the experiments, the curing reaction mechanism of the epoxy resin matrix was investigated.
