Carbon fiber reinforced plastics (CFRP) have microscopic inhomogeneity. It is necessary to consider the effect of inhomogeneity in order to improve accuracy for analysis of CFRP structures. In this study, we constructed multiscale simulation method for CFRP plate structure using commercial FEM code, Abaqus. Multiscale simulation consists of microscopic, mesoscopic, and macroscopic scales. In microscopic scale, we obtained material properties of unidirectional fiber tows from material properties of fiber and resin. In mesoscopic scale, CFRP plate stiffness including out-of-plane shear stiffness was calculated for analysis with shell element. Macroscopic analysis was conducted by using plate stiffness and shell elements. Finally we compared results of three-point bending tests including short beam tests with shell element analysis. In three-point bending tests and analysis, we changed aspect ratio by changing jig span. In both of them, when aspect ratio decreases, apparent bending modulus decreases. Analysis showed good agreement with experiments.
