Abstract
In this study, using finite difference method to simulate deformation of woven carbon fabrics. In this case, woven carbon fabrics all weaving by plain weave. After weaving, the mechanical behavior can’t be considered isotropic material. It is required use other ways on the mechanical analysis and discussion, and in this study, will treated woven carbon fabrics as an orthotropic material to analyze mechanical behavior. Past literature discovered when a woven carbon fabrics deformed by bias test. It will show three different zones. In zone A, the warp and weft yarns have both clamped. In zone B one yarn direction is clamped, the other direction is free end. In zone C, the warp and weft yarns have all free ends. Definition a dimensionless number β, when the value is equal to 1, woven carbon fabrics will be considered the deformation of isotropic material, and in this study, when the value is less than 1, even closer to 0, woven carbon fabrics will be regarded as an orthotropic materials. This study will use finite difference method to simulate a bias test of 2D woven carbon fabrics in the case of β less than 1.
