摘要(Abstract)：

采用化学镀的方法在碳纳米管表面镀覆一层铜纳米颗粒,旨在改善其与铝基体之间界面结合性能,从而提高复合材料最终的力学特性,用常压烧结与高温模压、热挤加工相结合的工艺制备碳纳米管增强铝基复合材料,通过X线衍射仪、扫描电子显微镜、透射电子显微镜等对经过表面化学镀的碳纳米管粉末和复合材料的结构与性能进行表征测试。结果表明:随着碳纳米管质量分数的增加(0~4.0%),复合材料的硬度逐渐上升,抗拉强度先升高后下降;当质量分数为3.5%,分别可达到207.74HB和453.84 MPa,比纯铝提高了230.6%和326.9%,相比不经任何处理直接添加碳纳米管制备的复合材料提高了47.5%和23.55%。
