Vacuum Hot Pressing and Properties of PP/HGMS Composite

  • 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/cm3,并且具有35.64 MPa的压缩强度和1.41%的吸水率。
    Abstract: 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 of composite fractures is analyzed. The results show that the PP/HGMS composites with excellent properties can be prepared by vacuum hot pressing. When the volume fraction of HGMS reaches 50%, the density of the composite decreases to 0.645 g/cm3, the compressive strength reaches 35.64 MPa and the water absorption is 1.41%.
