Ballistic Impact Resistance of Multi-Layer Textile Fabrics

Abstract

Experimental and theoretical work on the transverse ballistic impact of Kevlar and nylon fabrics is presented in two parts. Part I is an experimental investigation into (a) the relation between the multi-layer and single layer impact; (b) the effect of fabric finishes; and (c) the effect of weave. A simple model of impact together with the experimental data showed that inter-layer effects are of second order. High friction finishes and bonding agents were found to be detrimental to the performance of Kevlar. Triaxial fabrics were found to be inferior to biaxial fabrics. Part II describes the development and applications of computer models of impact using both characteristics and finite element methods. (Author)
