Analysis of Ballistic Impact Performance and Shear Effect on Elastomeric and Thermoset Composites

This study proposes a new theoretical model for high-velocity impact in two kinds of targets, Kevlar/elastomer and Kevlar/epoxy composites, comprehensively discusses compares these. In this analysis, with the aid hyperelasticity theory, energy absorption equations are derived based on linear nonlinear behavior constituents to assess dependence ballistic limit interaction first, second, third, fourth layers laminate each other. Furthermore, investigate matrix effect in-plane shear, tensile tests were performed at [Formula: see text] direction both composite laminates. The results indicate that adhesion Kevlar fibers rubber is more substantial than their epoxy matrix, increasing failure shear strain elastomeric composites reducing debonding between fiber which led greater velocity. experimental verified proposed confirmed its precision. With model, thickness targets was investigated.
