Abstract: The shock-wave properties of ED-10 epoxy resin have been studied using VISAR and PDV multiple-channel laser interferometers. The Hugoniot of epoxy resin and pressure dependence of sound speed has been obtained and it has been shown that the structure of a shock-wave front corresponds to the model of a Maxwell viscous-elastic body with a typical relaxation time of tangential stresses of 0.3 $\mu$s. The spall strength has been measured and its dependence on the strain rate in a sample upon pulse tension has been determined.
