【摘要】 通过溶液共混法和"真空处理—预固化-破碎-模压-加热固化"的方式制备了石墨/环氧树脂高填充复合材料。使用光学显微镜对其形貌进行了分析,研究了石墨含量对复合材料导电性能和力学性能的影响规律,确定了一种制备石墨/环氧树脂高填充复合材料可行的方法。结果表明,所制备的复合材料中石墨含量达80%,体积电阻率为10-2Ω.cm。逾渗过程发生时所制备的复合材料力学性能最佳。更多还原

【Abstract】 High loading graphite/epoxy resin composite was prepared by solution hybrid method.Several post-processing methods could be used such as casting molding,mould press-heat cure,vacuum degassing-heat cure and vacuum degassing-mould press-heat cure.The morphology and structure were characterized by optical microscope.A feasible method was used to prepared high loading graphite/epoxy resin composite.It was shown that the content of graphite reached to 80 wt%,the volume resistivity was 10-2 Ω·cm.When the percolation process occured,mechanical properties of the composite material was the best.更多还原
