Evaluating the mechanical properties of a CFRP tube under a lateral impact load using the split Hopkinson bar

The mechanical properties of a CFRP tube, such as strength, stiffness, and energy absorption, are investigated under a lateral impact load using the split Hopkinson pressure bar. In order to obtain the load–displacement curve, a ramped wave was applied to the specimen. It was observed that the ramped incident wave can be used for evaluating the mechanical properties of a CRRP tube under a lateral impact load. The dependence of the displacement rate on the properties mentioned above is also discussed. The result indicates that crack propagation behavior strongly depends on the displacement rate.
