Compression Property of Roll Core Sandwich Panel

Compression test of roll core sandwich panel was carried out by varying the cell wall tickness and the cell size. From obtained results, it was found that compression strength and energy absorption were proportional to the square of core density and inversely proportional to the cell size. By comparing with the compression property of honeycomb core sandwich panel, it was observed that the roll core sandwich panel was superior to the honeycomb core sandwich panel. It was because the roll core sandwich panel had the larger reinforced area by constraint of cell deformation than the honeycomb core sandwich panel.
