A cell model of glass fiber reinforced epoxy resin matrix composite was established under the environment of finite element software Abaqus. Unidirectional deformation in six directions applied to the cell, and the average stress and average strain of the cell was obtained. According to the homogenization idea of the composite, the material for cell was supposed to three-dimensional orthogonal anisotropy homogeneous material. According to the relationship between elastic deformation stress and strain, the elastic modulus of homogeneous material were obtained as the elastic modulus of composite material. Compared with elastic modulus obtained by the experimental measurement or theoretical calculation, the effectiveness of the method was verified.
