Longitudinal fibers, also called middle-end fibers, can be inserted into braided fabric during the braiding process. In the previous paper, it was confirmed that the braided composite with the middle-end fibers had superior mechanical properties compared to the braided composite without them. In this paper, a numerical analysis method is proposed for estimating the mechanical behavior of braided composites. This model considers the continuity and orientation of fibers. With this model, the tensile properties and fracture behavior of braided composites with the middle-end fibers were estimated and compared with the experimentdata presented in the previous papers. The tensile properties predicted by this method agreed well with the experimental data. Moreover, it was clear hat the fracture process of braided composites with the middle-end fibers could be simulated using this analysis method.
