Effective Viscoelastic Behavior of Particulate Polymer Composites at Finite Concentration

  • 摘要: 聚合物材料通常表现为粘弹性性质.为了改进聚合物材料的力学性能,通常将某种无机材料以颗粒或纤维的形式填充到聚合物中,从而得到增强、增韧的聚合物基复合材料.提出了一个新的细观力学模型,用于预测颗粒增强聚合物复合材料的有效粘弹性性质,尤其针对高体积百分比的颗粒夹杂复合材料,该方法基于Laplace变换和双夹杂相互作用的弹性模型.计算了玻璃微珠/ED-6复合材料的有效松弛模量以及恒应变率下的应力应变关系.计算结果表明在高体积百分比下该文方法比基于Mori Tanaka方法预测的粘弹性效应明显减弱.
