In view of the important influence of void defects on the mechanical properties of materials, the off-axis tensile mechanical properties of 3D five-directional braided composites with voids are studied by introducing randomly distributed void defects into the meso-scale model of material. For two specimens with typical braided angles, the effect of void contents on the on-axis mechanical properties was discussed and the appropriate void contents were determined by comparing with the available experimental data. Based on the periodic boundary conditions, the off-axis load was applied to obtain the stress-strain curves of the material under different off-axis angles and the strength properties were thus predicted. The meso-scale damage initiation and evolution processes of the composites under typical off-axis angles were simulated and the failure mechanism was analyzed in detail, which provides a proper reference for the numerical analysis of void defects and off-axis loading problems of other composite structures.
