The objective of this paper is to investigate into characteristics of the impact energy absorption of ISB panels for the case of the free boundary conditions. In order to examine into characteristics of the impact energy absorption, drop impact tests have been performed. Through the results of the impact tests, The absorbed impact energy per weight, the deformation characteristics of the ISB panels have been quantitatively examined. The experimental results of the ISB panels have been compared to that of SPFC 780 sheet. The impact energy of the tests ranges from 37.1J to 109.1J. From the results of the experiments, it has been shown that ISB panels have a high absorbed impact energy per weight about 9% in comparison with SPFC 780 sheet.
