This study investigated the blast-mitigation effects of an aluminum honeycomb composite panel on the deflection of a target steel plate, by conducting a series of close-in explosion tests in which a fragment impact was considered. In the close-in explosion tests, aluminum was used as an upper sheet of the honeycomb panel, and the honeycomb panel was set on a steel plate. A steel ball was set at lower or inside of a spherical high explosive of Composition C-4 to simulate a fragment impact. The test results revealed that the position of a steel ball affected the perforation of the aluminum sheet and the blast-mitigation effect by the honeycomb panel.
