The evaluation of the stress field distribution of warp-reinforced 2.5D woven composites using meso-scale voxel-based model is described. The idealized geometry model is established by using measured parameters from the CT image. Comparison between voxel-based finite element method and experimental measurements is included. The results show that the proposed meso-scale voxel-based method is capable of accurately predicting the mechanical properties of warp-reinforced 2.5D woven composites, validated by the comparison of the initial modulus, max stress as well as the failure modes. Also, the numbers of representative volume element have an important effect on mechanical behaviors of warp-reinforced 2.5D woven composites.
