摘要
采用聚丙烯、石墨、碳纤维 (CF)制备出满足实际应用要求的高导热、高强度复合材料。实验结果表明 ,石墨和碳纤维在基体中的合理分布能显著提高复合材料的导热性能和力学性能。当聚丙烯和石墨的质量比为 5 0 /5 0时 ,添加 3 .3 3 %的碳纤维 ,其热导率为 2 .1W /(m·K) ,拉伸强度达到 5 1.49MPa。
Composites of polypropylene with graphite and carbon fi ber were prepared. It was showed that good thermal conductivity and mechanical p roperties can be obtained with fine dispersion of graphite and carbon fiber. Whe n the mass ratio of polypropylene and graphite was 50/50, 3.3 wt % (based on the former two) CF was introduced, the thermal conductivity of composite mater ials reached 2.1 W/(m·K), and tensile strength was 51.49 MPa.
