Analytical Investigation on the Tensile Behavior of Hybrid Plain-woven Fabrics

Nowadays، fabrics produced from admixture of different yarns are used for industrial purposes such as composite materials. Since the tensile properties of these fabrics are important، in this research a mechanical model based on Leaf and Kandil model for hybrid plain-woven fabrics is proposed. In this model، the initial load-extension behavior of hybrid fabrics is calculated from the yarn mechanical properties and fabric structure by energy method. In order to evaluate the modeling predictions، the values of experimentally obtained mechanical properties of simple and hybrid fabrics with different admixtures of basalt and nylon، are compared with the theoretical model results. Comparing the results shows that there is a good correlation between the proposed model prediction and experimental results. In addition، comparing the results of simple and hybrid fabrics indicate that difference between theoretical and experimental results is due to other sources of errors and not necessarily due to the proposed model.
