Orthotropic properties of diagonally structured woven fabrics

Woven fabric as a complex structured orthotropic material has two axes of symmetry: in the warp and weft direction. In the ideal case of symmetrical woven fabric (in plain weave and in its derivatives) orthotropic main axis lay on the axis of structural principal directions of the fabric, but in the case of asymmetric woven fabric - geometrical diagonally structured woven fabric (in twill and satin weave and in their derivatives) at normal stress, axis displacement i.e. angular deformation occurs. This phenomenon is not the result of shear stress, but rotation of orthotropic main axis with regard to the axis of structural principal directions of the fabric. With this research, the knowledge about the behaviour of asymmetric woven fabrics at normal stress will be expanded, which will lead to insights about important material properties that will define its qualitative and use values in the field of small and large surface axial stress.
