Yarn Pull-Out as a Mechanism for Dissipation of Ballistic Impact Energy in Kevlar KM-2 Fabric, Part 2: Prediction of Ballistic Performance

Abstract

The energy absorbed in ballistic fabrics is modeled by assuming yarn pull-out including yarn uncrimping and translation as the primary energy absorption mechanisms. Using a semi-empirical model of yarn pull-out based on laboratory tests predictions for ballistic performance of fabrics are compared to ballistic test results. It is demonstrated that quasi-static pull-out results can be correlated quantitatively with yarn pull-out during ballistic impact.
