Abstract

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
