For the theoretical estimation of macroscopic elastic moduli of particulate-reinforced-plastic, there are three important factors to be considered; (1) the shape of filler-particles, (2) the orientation distribution of fillers, and (3) the interaction among fillers. In industry, various shapes of fillers are used for the reinforcement of plastics. Except for spherical fillers, it is impossible to neglect the orientation distribution of fillers. The filler-particles can be added up to such an amount that the effects of fillers appear remarkably, so that the interaction among the fillers cannot be neglected in general. We can evaluate the effect of the shape of filler by applying Eshelby's theory, if the shape of filler can be approximated to ellipsoid. However, the factors (2) and (3) have never been analyzed in a satisfactory manner. In this paper, a self-consistent method utilizing Eshelby's theory is proposed. It is shown that by using this method the effects of orientation distribution as well as the interaction among fillers can be evaluated in terms of distribution functions.
