用化学镀的方法对碳纤维进行了表面镀铜处理。采用热压法制备碳纤维增强Cu-Ti3SiC2复合材料,研究了碳纤维含量对复合材料的电学及力学性能的影响。结果表明:添加的碳纤维体积分数小于8%可均匀分散在复合材料中。复合材料的最大的导电率为4.39×106S/m,当碳纤维的体积含量为6%时,复合材料的最大的弯曲强度和压缩强度为421 MPa和623 MPa。复合材料的强化机制主要为纤维拔出和颗粒弥散。 The method of electroless plating carbon fiber surface copper plating treatment. The carbon fiber reinforced Cu-Ti3SiC2 composites were prepared by hot pressing. The effects of carbon fiber content on the electrical and mechanical properties of the composites were studied. The results show that the volume fraction of carbon fiber added less than 8% can be uniformly dispersed in the composite. The maximum electrical conductivity of the composites is 4.39 × 106S / m. When the volume fraction of carbon fibers is 6%, the maximum flexural strength and compressive strength of the composites are 421 MPa and 623 MPa. The strengthening mechanism of composite materials is mainly fiber pull-out and particle dispersion.
