| 摘 要： | 用动态扭振法对环氧树脂-聚酰胺和环氧树脂-聚酰胺-玻璃微珠体系在四个不同温度和不同玻璃微珠含量的等温固化行为进行了测试。通过凝胶化时间tg 用F lory 理论估算了它们固化反应的表观活化能, 并考察了玻璃微珠含量对固化的影响。用非平衡态热力学涨落理论描述了它们的等温固化过程, 从而用有限的数据来预估树脂体系的固化, 理论曲线和实验曲线有很好的符合。

| Abstract: | The isothermal cure behavior of epoxy-polyam ide and epoxy-polyam ide-glass m icroballsw ith varying composition w as investigated by the dynam ic torsional vibration method in four varioustemperatures. The gel time tg and apparent activation energy Ea of cure reaction w ere estimated. Theeffect of glass m icroball on gel time and apparent activation energy has been considered. The nonequilibrium thermodynam ic fluctuation theory can successfully describe and p redict the mechanicalproperties of the resin system w ith or w ithout glassm icroball during the curing p rocesses. |
