摘　　要：采用熔融挤出法制备了短碳纤维/聚乳酸复合材料,通过力学性能测试、SEM和固体流变分析等方法研究了短碳纤维含量对复合材料力学性能、体积电阻率和硬度的影响。结果表明:在实验范围内,随着短碳纤维含量的增加,复合材料的力学性能提高,体积电阻率显著下降,而其洛氏硬度变化不大。Short carbon fiber/PLA composite was prepared by melting extrusion.The effects of carbon fiber content and coupling agent content on mechanical property,processing property and crystallization property of the composite were studied by mechanical property test,SEM,dynamic mechanical properties measure analysis.The results showed that in the experimental range,with the increase of short carbon fiber content,the mechanical property of the composite increased obviously,the volume resistivity of composite decreased remarkably.The Rockwell hardness of composite don＇t change with the short carbon fiber increased.
