摘要
The main purpose of the study is to present a new concept in assessing impact of the woven fabric on its electroconductive properties. Fabric is treated as two-component composite i.e. anisotropic medium containing empty spaces filled with air shaped anisotropic ellipsoids. The method can be also used to assess the compactness, which is one of the features of Van der Pauw structure. The method allows one to determine resistivity of material composed of interlaced yarns as the material property. Analysis of chosen woven fabric structure was conducted. Percentage surface cover of the fabric by warp and weft yarns and depolarization factor were determined. It was found the woven fabrics satisfy requirements described in Van der Pauw structure. Using Van der Pauw method resistivity of material composed of interlaced yarns as a feature of the material was calculated for all woven fabrics. Resistivity of material is one of the required parameter in multiphysics simulation software used to understand physical phenomena of the designed object.
