【摘要】 研究了填充ＰＥＣＨ复合体系的弹性模量在不同测试温度和拉伸速率下随填料体积分数和粒子间距离的变化规律，同时考察了粒子堆积方式对弹性模量的影响，并运用逾渗理论解释了实验结果。研究结果表明，测试温度和拉伸速率对体系的弹性模量有显著的影响，临界粒子间距离是温度和拉伸速率的函数，而且与粒子堆积方式相关，拉速和温度对填充聚合物复合体系中逾渗过程的影响具有等效性。更多还原

【Abstract】 Elastic Modulus of Wollastonite filled PECH composites have been measured under different test temperature and tensile rate. It has been found that elastic modulus vary with filler volume fraction, interparticle distance and fillerpacking state. Elastic modulus shows divergence on the curve of elastic modulus versus interparticle distance. The critical interparticle distance shows the dependence of test temperature, tensile rate and filler packing parameter. The effects of tensile rate and test temperature on elastic modulus are similar. These results have been interpreted by applying percolation theory.更多还原
