Textile Ballistic Performance (Data Base)
Abstract
Nylon and Kevlar textiles are examined for their performance against impact by a 1-gram projectile, when subject to impact velocities up to 200 m/s. The textiles are of varying areal density, and of varying layer composition and their performance is examined theoretically and experimentally. The theoretical models have been previously developed and are the characteristics model, membrane finite element and a multilayer finite element; the experimental facility had also been previously established and this report is aimed at correlating the experimental and theoretical facilities and to establish a data base of results. It was quickly found that the theoretical models favoured nylon over Kevlar for ballistic performance, whereas experimentally Kevlar is superior. It is also shown that the deformation process is correctly modelled and this then suggests that the fracture criterion must be reconsidered; possible fracture mechanisms to be included in textile failure criterion are stated for future consideration.
