Abstract
This paper aims to study the multiple low-velocity impact (LVI) response and compression after impact (CAI) performance of composite laminates subjected to different energy impacts. The study includes an analysis of the effect of the first impact with different energy on the second impact with the same energy at the same location. The results show that the first impact has a certain enhancement effect on the impact resistance of the laminates when the impact energy is very small. Overall, with the increase of the first impact energy, the impact resistance and the residual compressive strength of the laminate significantly reduce.
