采用真空辅助喷涂的方法制备了相对于玻纤质量分数1%、3%的碳纳米纤维/玻纤/环氧树脂基复合材料,并对其机械性能、耐固体粒子冲蚀磨损性能与纯环氧树脂(EP)、玻纤增强环氧树脂(FRP)进行了对比研究.结果表明:1%、3%碳纳米纤维的加入使得复合材料的拉伸强度达到72MPa、70MPa,相对于EP分别增加了20%、16.7%,相对于FRP分别降低了32.7%、30.7%;弯曲强度达到150MPa、178MPa,相对于EP分别增加了40.2%,66.4%,相对于FRP分别降低了19.8%、4.8%;侵蚀磨损试验中质量损失相对于FRP分别降低了75%、86.7%,在对复合材料机械强度影响较小的前提下大大提高了复合材料的耐磨损性能.
