Electrical conductivity tensor modelling of stratified woven-fabric carbon fiber reinforced polymer composite materials

Résumé

In this paper, a new multi-scale approach to predict the effective electrical conductivity tensor of a woven-fabric composite layer for frequencies lower than 10 MHz is presented. The result is then used to model the behavior of a stratified composite material composed by a pileup of woven-fabric layers with different relative orientations. To take into account the orientation and the anisotropy of the material, a 3-D multilayer hexahedral degenerated elements method is used to model the anisotropic thin plate. This approach enables to take into account random distribution of carbon fibers in the yarns, 3-D effects, and electric percolation threshold with an acceptable numerical cost. The developed model is then validated by results for one anisotropic thin layer.
