DEFORMATION RATE UNDER SHOCK COMPRESSION IN POLYMERIZED EPOXY RESIN

Abstract

The properties of the Etal-370 epoxy resin polymerized with the Etal-45M hardener are investigated by laser interferometry (VISAR) under shock compression in the pressure range from 0.92 to 2.55 GPA. The shock adiabat in the mass velocity coordinates, i.e. the velocity of the shock wave, is obtained. It is found that the power dependence of the deformation rate in the shock wave front on the pressure behind its front has an index of 6.3, which significantly exceeds the generalizing degree of 4 obtained for solid materials.
