Abstract
Finite element (FE) model of woven fabric green composites considering matrix/yarn sliding friction is adopted to simulate deformation behavior under simple tension in this study. In this model, certain gap were created on the interface between yarn and matrix, wrap and weft yarns. Each interface could contact and interact each other through deformation process. The interaction can be generated by the sliding friction contact surface. The deformation simulation under simple tension was carried out using a commercial explicit dynamic FE code, LS-DYNA. To clarify the obvious deformation behavior and a surface unevenness configuration on the composite, tensile deformation behavior was simulated for woven fabric green composite with fiber orientation θ = 45° to tensile direction. The validation of the FE model with a gap was confirmed compared with the FE models having a gap and non-gap at the interface.
