Abstract
As one of the problems in the modeling of the 3D woven composites is given by geometric yarn interpenetrations, this paper presents a solutions for a E-Glass 3D woven case. The solution is validated by comparison of the corrected geometry obtained from specific adjustments and the geometric measured from literature. The 3D model is generated using the WiseTex software, which creates approximate fabric models with the constant cross-section shapes of the yarns. According to experimental measurements, the yarn cross sections are modified to approach the actual shapes and hence adequately represent the intra-yarn fiber volume fraction. The yarn interpenetrations are corrected by adjusting nodes of discretized yarn contours. The FE analysis results show good agreement with the experimental data for the elastic properties of the composites.
