OS1303 Mechanical Properties of Soft Epoxy Resin for Flexible Protector

Abstract

We propose flexible sports protectors whose outer shells harden only under impact loading by virtue of the strain rate effect on mechanical properties due to the viscoelasticity. In the present study, we investigated the compressive mechanical properties of soft epoxy resins as an outer shell material of flexible sports protectors. The effect of the strain rate on the compressive behavior of the soft epoxy resin was clarified by conducting static compression and split-Hopkinson-pressure-bar (SHPB) tests. The experimental results reveals that the soft epoxy resin is suitable as outer shell material.
