The overall elastic properties of fiber reinforced composite are of primary importance for practical applications. In order to obtain the overall elastic properties, a homogenization procedure based on continuum micro-mechanics is usually applied to a representative volume element (RVE) representative of the whole composite. In this study, we first employ a modified random sequential adsorption algorithm to generate the complex geometry of a random fiber composite. Second, we investigate the effect of the interaction between two over-crossing fibers on the overall elastic properties of the composite. Third, we evaluate the overall elastic material properties of the composite using the finite element method for continuum micro-mechanical analysis.
