Abstract:

为了改善Kevlar缝线缝合复合材料的耐湿热性能,采用化学接枝烯丙基的方法对Kevlar缝合线进行表面改性处理。通过力学测试、扫描电子显微镜(SEM)、光电子能谱分析(XPS)对表面改性的纤维进行表征。实验结果表明,化学处理的Kevlar缝线表面变得粗糙,缝线表面氧元素的含量提高23%,在合适的处理条件下,缝线的拉伸强度降低很小。同时通过测试干、湿态下炭纤维/双马来酰亚胺树脂缝合复合材料层压板的层间剪切强度,研究了化学表面处理的Kevlar缝线对缝合炭纤维/双马来酰亚胺树脂复合材料界面性能的影响。测试结果显示,表面处理后Kevlar缝线缝合的复合材料的吸湿率降低约52%,湿态层间剪切强度保持率提高15%。
