| Abstract: | This paper presents a Hopkinson bar-bar impact tensile apparatus and the measure technique. Then, computing formula of stress and strain are deduced. The impact tensile properties of CFRP and GFRP laminates have been studied using Hopkinson bar-bar apparatus. The stress-strain curves of the two laminates and the mechanical parameters such as failure strength, Young′s modulus and fracture strain under different strain rate are given. A tentative knowledge for the dynamic mechanical properties and failure mechanism of the composite laminates under impact tensile has been constituted. |
