摘　　要：采用熔融共混与注塑成型的方法制备了聚丙烯/氧化聚乙烯蜡/剑麻纤维(PP/OPE/SF)复合材料,研究了氧化聚乙烯蜡(OPE)对复合材料力学性能的影响。结果表明,OPE显著提高了复合材料的冲击强度,适当添加量的OPE增强了PP/SF的界面键合,提高了复合材料的拉伸强度和拉伸模量。Composite based on polypropylene （PP） and sisal fiber（SF） containing oxidized polyethylene wax （OPE） is prepared by melt mixing and injection molding. The mechanical behaviours of the PP/OPE/SF composite are systematically investigated. The results show that the izod impact strength of the composite is evidently elevated after OPE is added into PP/SF system. On the other hand, the proper amount of OPE enhances the interracial interaction between the reinforcing SF and PP matrix. It leads to.the improvement in tensile strength and modulus of the composite.
