Performance of interlayer toughened carbon fiber/epoxy composites of low areal density PA66 fiber veil

  • 摘要: 为改善碳纤维/环氧(CF/EP)复合材料的层间断裂韧性,通过湿法成网技术制备出四种不同面密度的聚酰胺66纤维网纱(PA66V),随后将增韧网纱插入碳纤维单向布层间,借助真空辅助树脂灌注(VARI)工艺固化成型制备得到CF/EP复合材料。文中测试了增韧前后CF/EP复合材料的I型层间断裂韧性(GIC)和II型层间断裂韧性(GIIC),结合断面SEM照片揭示了PA66V引入后CF/EP复合材料的增韧机制,并研究了网纱的引入对CF/EP复合材料其它力学性能的影响。结果表明,面密度为4 g/m2 PA66V的加入将CF/EP复合材料的GICGIIC分别提升了13.6%和139.8%,其增韧机制主要包括PA66纤维的桥接拔出、塑性变形以及引发裂纹偏转等;此时,CF/EP复合材料的层间剪切强度和拉伸强度也分别提高了6.5%和5.2%。
