将环氧树脂基体与氨基化碳纳米管(MWNTs)复合,制备了碳纤维/氨基化碳纳米管-环氧树脂(CF/MWNTs-EP)复合材料.表征CF/MWNTs-EP三相复合材料的断面,并在标准条件下测试其冲击、拉伸等力学性能,研究了耐老化性能.结果表明:氨基化碳纳米管的加入明显提高了材料的耐盐雾性、耐热氧老化性和耐湿热性能.氨基化碳纳米管的加入改善了纤维与基体树脂间的界面性能,同时,促进了环氧树脂的固化,降低孔隙率,导致耐老化性能显著提高.当MWNTs-NH2的添加量(质量分数)为1.0％时,在72 h和168 h不同盐雾时间下,三相复合材料的耐盐雾老化性比CF/EP复合材料分别提高了61.8％和67.5％.在48 h、96 h和168 h热氧老化时间下,三相复合材料的耐热氧老化性比CF/EP复合材料分别提高了43.5％、48.5％和41.7％.在72 h和168 h不同湿热时间下,三相复合材料的耐湿热老化性比CF/EP复合材料分别提高了52.8％和60.0％.
