Abstract: The tensile impact experiments were carried out at different strain rates and temperatures by using of Hopkinson bar-bar tensile impact apparatus and universal tester.The stress-strain curves were obtained based on one-dimension stress wave theory.The results showed that the tensile behavior of Kevlar~964C is strain rate and temperature dependent.At the same temperature,the failure stress,unstable strain,initial elasticty modulus and specific fracture strain energy density increase with increasing strain rate.At the same strain rate,the failure stress,unstable strain and specific fracture strain energy density increase with increasing temperature,but initial elasticty modulus decreases with increasing temperature.The mechanism of strain rate and temperature dependence of tensile behavior was analyzed based on the above experiments.
