| 摘 要： | 运用自行研制的浸润特性测试系统,研究了环氧树脂对单向纤维集束的浸润行为,分析了纤维体积含量、树脂温度、纤维种类及纤维表面浸润剂等因素对浸润的影响规律.研究表明,增加纤维体积含量、升高树脂温度、去除纤维表面浸润剂均可加快环氧树脂对纤维集束的平均浸润速率.研究结果对指导复合材料成型工艺的合理设计、开发浸润特性表征新方法具有重要的意义.

| Abstract: | Understanding the wetting behavior of resin in fiber assemblies is critical for predicting and improving the fabrication performance of composites. According to capillary rise method, the wicking flow in unidirectional fiber bundles was characterized through measuring the mass gain in fibers at different time. The effects of many factors on the wicking performance of epoxy resin in unidirectional fiber bundles were investigated, such as the volume fraction of fibers, the type of fibers, the temperature of resins and the sizing on fibers. The experimental data suggest that the wicking velocity of resins could be increased with increasing fiber volume fraction, with enhancing temperature and by removing the sizing on S-2 glass fibers. |
