The impact energy dissipation analysis of woven para-aramid fabrics

Abstract

This work investigated the propagation characteristics of impact energy along the plane of woven para-aramid fabric using the two-dimensional thin-plate spline method. To evaluate fabric deformation at different layer numbers, weights with various tip types were dropped from a specific height. We discovered the energy propagation characteristics within the fabric planes by examining shape changes in response to deformation. To further investigate energy propagation, we evaluated the bending energy of the fabrics and determined the expansion factors. Our findings show that impact energy travels through the fabric along the directions of the warp and weft strands, which are interwoven at right angles.
