3D meso-structural composites with three layers were constructed using 3D modeling software Pro/E, and the static anisotropic characteristics of the composites under lateral compression in warp and weft directions were simulated by using finite element analysis software ANSYS. The mechanical properties of the composites under lateral compression were predicted by analyzing the stress and strain distribution of fiber and resin in the composites under lateral compression load. The anisotropic characteristics of composites were then analyzed. Results showed that the lateral compression property of the composites was anisotropic, and the lateral compression performance in weft direction was better than that in warp direction. In the composite, fiber bears more load, and the resin undergoes greater deformation. Fibers whose axial direction is parallel to the lateral compression direction bears greater load, while fibers whose axial direction is perpendicular to the lateral compression direction bears less load.
