摘　　要：为了研究多官能度环氧树脂(AFG-90)对环氧树脂共混体系耐热性能的影响,通过动态机械分析仪测试了其不同加入量的共混树脂固化物的玻璃化转变温度(Tg)。结果表明:AFG-90和普通环氧树脂有很好的相容性,其固化物的Tg随AFG-90加入量的增加而增加,并表现出1个最佳值范围;而固化物的初始模量基本保持不变。In order to study the effects of multi functional epoxy resin on thermal resistance of mixed epoxy resin system, Tg of the cured systems were analysied by dynamical mechanical analyzer. The results showed that the epoxy resin systems are with good comparability each other and the Tg of cured epoxy was paralleled with AFG -90 addition. But the modulus was the same no matter how much AFG-90 addition changed.
