摘　　要：以抗冲共聚聚丙烯(IPC)为基体,对IPC/椰壳纤维与IPC/碳酸钙(CaCO3)复合材料的力学性能进行对比研究,并采用扫描电子显微镜(SEM)观察了它们的断面形貌,分析了椰壳纤维与CaCO3在IPC中的分散、粘结效果。结果表明,IPC/椰壳纤维复合材料在力学性能方面比IPC/CaCO3复合材料具有明显的优势,且随着填料含量的增加,优势越来越明显。SEM结果表明,椰壳纤维与IPC的界面粘结性良好,而CaCO3与IPC的界面粘结性很差,这是IPC/椰壳纤维与IPC/CaCO3复合材料力学性能有较大差异的一个重要原因。Impact polypropylene copolymer（IPC） was used as matrix, and the mechanical IPC / CaC03 composites were compared. The fracture surface morphologies of the composites properties of IPC / coir fiber and were observed by using scanning electron microscope（SEM） and the dispersion and bonding effect of CaCO3 and coir in IPC were analyzed. The results show that the mechanical properties of IPC /coir composites have obvious superiority than that of IPC / CaCO3 composites, and the superiority more obvious with the increase of the mass fraction of the fillers. SEM results show that the interfacial adhesion between coir fiber and IPC is better, and it is poor between the CaCO3 and IPC, which is an important reason of mechanical properties are quite different between them.
