Shear angle effect on the engineering constants of woven fabrics

Fabrics play a key role when used as both reinforced material for composites and simply as apparels. In textile industry, fabric geometrics and weave pattern play a key role in the overall behaviour, mechanical response and general feel and texture of a piece of fabric. The engineering constants of are highly important parameters since the materials are largely orthotropic in nature. It is therefore, pertinent to investigate the effect of some key parameters on the engineering constants of a material, especially when they are used for HSE critical purposes such as reinforced composites employed in the design of aircraft wings, fuselages and other parts. The effect of shear angle on the six engineering constants is investigated using Ansys Material Modeler. Material properties are shown in Table 2 and gotten from measurement from the lab. The model was automatically achieved by inputting the textile geometrics, and generating the RVE, applying the boundary conditions, periodicity of the model and running the simulation. The material properties are given in Table 1, and are deduced from experimental data. To further expound the work, the effect of geometric properties such as fabric thickness, yarn width and yarn spacing will be explored in subsequent work.
