摘　　要：以聚丙烯(PP)为基体,以高性能空心玻璃微珠(HGMS)为填充体,通过真空热压成型法制备聚丙烯/空心玻璃微珠复合材料。研究了HGMS填充体积分数对复合材料的密度、拉伸强度、压缩强度、剪切强度和吸水率的影响,分析了复合材料断口的微观形貌。结果表明,采用真空热压成型法能够制备性能优良的PP/HGMS复合材料。当HGMS体积分数达到50%时,复合材料的密度降低到0.645 g/cm^3,并且具有35.64 MPa的压缩强度和1.41%的吸水率。The PP/HGMS composite is prepared by vacuum hot pressing with polypropylene(PP)as the matrix and high-performance hollow glass microspheres(HGMS)as the filler.The effects of HGMS filling volume fraction on the density,tensile strength,compressive strength,shear strength and water absorption of composites are studied,and the micro-morphologies ofcomposite fractures is analyzed.The results show that the PP/HGMS composites with excellent properties can be prepared byvacuum hot pressing.When the volume fraction of HGMS reaches 50%,the density of the composite decreases to 0.645 g/cm^3,the compressive strength reaches 35.64 MPa and the water absorption is 1.41%.
