摘要整理
本研究旨在开发高性能防弹复合材料,以满足安全防护需求,特别是为国家安全部队提供更好的弹道防护装备。研究采用真空辅助树脂传递模塑(VARTM)工艺制备环氧树脂基混杂复合材料,增强体包括棕榈叶纤维、碳纤维和凯夫拉纤维,填料为SiC和Al₂O₃。本研究为大型综合性能评估项目的一部分,涵盖硬度、冲击强度、拉伸强度、微观结构和防弹性能等多项测试,但重点聚焦于拉伸强度分析。设计四种纤维体积分数配置:配置I(棕榈叶纤维10%+凯夫拉纤维10%)、配置II(棕榈叶纶5%+凯夫拉纤维15%)、配置III(SiC填料7.5%+Al₂O₃填料7.5%+凯夫拉纤维20%)、配置IV(SiC填料5%+Al₂O₃填料5%+凯夫拉纤维25%)。按照ASTM D 3039/D 3039M标准进行拉伸试验。结果表明:配置II的拉伸强度比配置I提高39.8%;配置IV的拉伸强度比配置III提高9.41%。研究结果为防弹复合材料的优化设计提供了重要的工艺参数和性能数据支撑。
