摘要：
In this paper, the repeated impact tests of composite sandwich panels were carried out by using In⁃ stron 9350 drop weight impact testing machine.The impact force-time, impact force-displacement curves and damage diagrams were obtained to investigate the dynamic response and damage accumulation character⁃ istics under single and repeated impact loads. The results show that the dynamic deformation and damage de⁃ gree of composite sandwich plates are accumulated, and the damage mode evolution may occur under repeat⁃ ed impacts. With the increase of repeated impact number, the bending stiffness of composite sandwich plates decreases gradually, and the structures are obviously weakened. © 2023 China Ship Scientific Research Center.
