| 摘 要： | 研究了聚丙烯(PP)/膨胀石墨(EG)/碳纤维(CF)复合材料的导热、力学以及加工性能.研究发现:当膨胀石墨的质量含量达到20％时,热导率是纯聚丙烯的2倍,但熔体流动性能有所下降；添加1％的聚乙烯蜡可以明显改善体系的熔体流动性能；将膨胀石墨与5％的碳纤维杂化使用,热导率达0.91 W·m-1K-1,是纯聚丙烯的5倍,熔体指数达到1.72 g/10 min,同时该复合材料具有较好的力学性能.

| Abstract: | The thermal conductivity,mechanical properties and processing property of polypropylene(PP)/expanded graphite(EG)/carbon fiber(CF) composite were studied.The results showed that the thermal conductivity of the composite with 20 % content of EG was 2 times that of pure PP,but its melt flow rate was decreased.The PE wax at the weight fraction of 1 % could improve the melt flow rate.When the content of carbon fiber was 5 %,the thermal conductivity reached 0.91 W.m-1K-1 and was five times of pure PP.The melt flow rate was 1.72 g/10 min and the mechanical properties were good. |
