摘要整理
陶瓷纤维复合材料在防护领域具有重要应用价值。本研究采用真空辅助树脂传递模塑(VARTM)工艺制备了具有夹层结构的稳定可靠的树脂增强纤维-陶瓷-纤维(RRFCF)复合材料,并系统研究了不同配置复合材料的力学性能。研究结果表明,玻纤增强塑料层的厚度参数(面板厚度ta和背板厚度tc)对RRFCF复合材料的独特力学性能具有显著影响。通过有限元模拟分析了不同配置RRFCF复合材料在加载条件下的应力分布规律。对Z型(ta<tc)和F型(ta>tc)两种RRFCF复合材料进行了疲劳性能测试,实验结果与模拟结果具有良好的一致性。研究发现Z型复合材料的弯曲强度和弹性模量均高于F型复合材料。此外,通过对比分析两种配置复合材料的性能差异,为RRFCF复合材料的工程应用提供了重要的指导意义。
