摘要
测试了高温条件下环氧树脂在玻璃纤维单向织物和碳纤维单向织物平面内的毛细浸润行为,探讨了温度、纤维-液面夹角对浸润特性的影响规律,分析了树脂与纤维接触形成的弯液面对测试结果的影响。研究结果表明,升高温度、增大纤维-液面夹角均有利于提高浸润速度和浸润质量。
The present paper deals with a primary study on the impregnation property in the plane of the unidirectional fabric with pure epoxy resin. The effect of the parameters on the dynamics of capillary impregnation was researched, such as temperatures, and fiber-resin surface impregnation angles. And a data treatment method was proposed to avoid the influence of meniscus at the bottom of the fabric. The results show that velocity of impregnation can be improved by increasing the temperatures and the impregnation angles.
