Dimensional Braid Structure Analysis And Computer Simulation

According to three dimension braided composites for braided technology-four-step and technology-two-step procedure, and with reference to theories of braided fabric geometry and force models, a geometric model is built. In this model, the cross-section of thread is described as a circle and thread path as a cubic B-spline. Braided-fabric structures in three dimensions are displayed by using solid-modeling techniques.Furthermore, by emulating the spatial location of yarn as computer 3D model, the yarn trend in three dimensions braided composites is shown conveniently and clearly.This paper offers the new way for braided -fabric structure simulation in three dimensions before braiding.By using virtual modeling language VRML to access simulating braided -fabric structure in three dimensions, the communication of braided composites information on web is easy.
