In the result obtained from the drop weight impact test of honeycomb core sandwich panel (Hereafter, HSP for brevity), the two concentric circles were observed in the dent formed on the face sheet. It was considered that the cell wall under beneath the outer circle supported the resistance force, because the cell wall was unbroken. Moreover, in the inside of the inner circle, the deep drawing process was observed. Therefore, it is considered that the cell wall arranged in the circumferential direction affects the local compression property of HSP. In this study, the sandwich panel where the cell wall was arranged in the circumferential direction was prepared. In addition, the sandwich panel where the cell wall was arranged in the radial direction was also prepared, because cell walls in the HSP arranged in various directions. By using these panels, serious of drop weight impact tests were carried out in order to investigate effects of the cell walls on the local compression property.
