In order to study the impact properties of the honeycomb sandwich panel (hereafter, HSP for brevity), current drop weight impact tests were carried out using 4 kinds of panels at several drop heights. Where, cores were used an aramid and its core heights were 22.5mm and 6.3mm. Surface boards of HSP were used the aluminum alloy (A1100P) and the fiber reinforced plastic (hereafter, FRP for brevity). Based on observed deceleration waves of the weight after the impact between the weight and the flat plate, absorption energies were calculated. When the energy absorption abilities were compared, HSP with flat plates of the aluminum alloy was superior to that with FRP. This was attributed to the fracture forms at impact applied point.
