ITAST (Iranian Textile Association of Science and Technology) Journal of Textiles and Polymers 2322-5203 4 1 2015 01 01 An Analytical Study of Initial Shear Behavior of Plain Woven Hybrid Fabrics 9 14 13884 EN Majid Tehrani Dehkordi Department of Carpet, Shahrekord University, Shahrekord Majid Tehrani-Dehkordi Hooshang Nosraty Journal Article 2016 03 16 During recent years, the fabrics made from different yarns have been used for industrial purposes such as composite materials. Given the importance of the shear properties of these fabrics, a mechanical model based on the Grosberg and Park's Model for hybrid plain-woven fabrics is proposed. In this model, using the Energy method, the initial load-shear angle behavior of hybrid fabrics is calculated from the yarn mechanical properties and the fabric structure. To evaluate the proposed model, the experimental results for initial shear modulus obtained from pure and hybrid fabrics of basalt and nylon are compared with the theoretical model results. A comparison of the results shows that there is rather a good agreement between the proposed model predictions and experimental results. http://www.itast.ir/article_13884_aef26bbca340bfeca3e5138aff165c59.pdf
