A point-based modeling scheme for the mesostructure of a two-step three-dimensional (3D) braided composite is proposed. The yarn path and the section profile are more realistic than the traditional mesh-based model, and the influence of the braiding process on the yarn path is reflected in the model. Owing to the point feature, the discretization of the matrix is very convenient after the reinforced structure is generated. The deformation and the failure of the braided composites can be directly simulated from the mesostructure model. Several examples, which include calculating the macroscopic elastic modulus and the high-velocity impact on the braided composite plate, show nice accuracies. The failure and fragmentation of the mesostructure can be well simulated with the point model and the mesh-free material point method.
