【Abstract】 Rubber high polymer has many dynamic features such as high electivity, low elastic modulus and visoelasticity, which are superior to the other materials. With the development of protective works, the advantages of such materials are accepted in the field of engineering. By using the experimental technology of Hopkinson pressure bar, the paper explores the dynamic features of four rubber complex materials composed of different admixtures when compact load exerted and analyses their better energy absorbing effect. In the experiments, the ratio of transmission amplitude to incident wave amplitude is found lower, which suggests a higher energy absorbing effect, esp. when polyester mixed cotton and nylon serve as energy absorbing material.更多还原
