Abstract
In several applications, the industrial and protective fabrics might be subjected to punching by the rigid sharp spikes. Fabric resistance to the penetration of the puncher at a constant rate was studied. The analysis of the factors influencing the resistance of the fabric and an explanation of the puncture mechanism were generated. Punching force-displacement curves were obtained and four noticeable fabric failure modes were observed. A special setup was designed so that the fabric sample can be subjected to the biaxial stresses during the puncture tests. This paper studies the puncture behaviors of the plain, twill 1/3, and twill 2/2 woven fabric designs. It was found that the increase in the number of fabric layers from one to three and the number of picks/cm from 17.6 to 27.2 would elevate the punching resistance and the punching energy by 354% and 333%, respectively, with the insignificant change in the values of specific punching force and energy. Plain weave design proved to have higher values than twill design. A high correlation was observed between fabric tensile strength, fabric Young’s modulus, fabric failure energy and its punching force and punching energy.
