摘要/Abstract

摘要： 为了预测不同形状颗粒增强复合材料的弹性常数,以碳化硅(SiC)颗粒增强环氧树脂为例,建立了不同颗粒形状的代表性体积元(RVE)模型,研究了不同颗粒形状及其体积分数对复合材料弹性常数的影响。通过改进的Halpin-Tsai模型,得出了形状因子与体积分数、颗粒体积和几何因子之间的关系式。有限元模型和改进的Halpin-Tsai模型计算的复合材料弹性常数结果相近,最大误差仅为4%。研究表明,改进的Halpin-Tsai模型可以用于预测碳化硅颗粒增强环氧树脂复合材料的弹性常数。

Abstract: In order to predict the elastic constants of particle-reinforced composites with different shapes, a representative volume element (RVE) model of different particle shapes was developed to investigate the effects of different particle shapes and their volume fractions on the elastic constants of the composites, taking silicon carbide (SiC) particle-reinforced epoxy resin as an example. And the relationship equations between shape factor and volume fraction, particle volume and geometry factor were derived by the improved Halpin-Tsai model. The results of the elastic constants of composites calculated by the finite element model and the improved Halpin-Tsai model are similar with a maximum error of only 4%. It is shown that the improved Halpin-Tsai model can be used to predict the elastic constants of silicon carbide particle reinforced epoxy composites.

Key words: Halpin-Tsai model, particle shape, volume fraction, elastic modulus, RVE model, composites
