以亚麻纤维作为增强纤维，以聚丙烯纤维作为树脂基体，通过模压成型工艺方法，制备了绿色环保型亚麻/聚丙烯复合材料，主要研究了纤维长度、模压温度及保温时间对复合材料拉伸性能及顶破性能的影响。结果表明：模压温度对复合材料性能的影响最显著；当纤维长度为5 mm、模压温度为180℃、保温时间为40 min时，复合材料的拉伸性能最优；在纤维长度为5 mm、模压温度为170℃、保温时间为40 min 时，复合材料的耐顶破性能最优。

Eco-environment flax/ polypropylene thermoplastic composite are prepared by compression molding process, in which the flax fibers as reinforcement and the matrix phases are come from polypropylene (PP) fibers. The effects of fiber length, molded temperature and holding time on the tensile and bursting performance of the composites are investigated. The results show that the molding temperature was the main factor to influence composite properties. The optimal tensile property of the flax/polypropylene composite is obtained in the parameters of fiber length 5 mm, molding temperature 180 ℃ and holding time 40 min. The bursting performance of the polypropylene/flax composites is come to the peak value when mentioned above parameters are 5 mm, 170 ℃ and 40 min.
