In this paper we describe an evaluation of multistage honeycomb panels, the buffer characteristics of which consist of the impact load, the deformation in the direction of the axis, the crush pattern and absorbed energy. The test specimens are the uniformtype laminated honeycomb panels of uniform cross-sectional area and the pyramidtype of variable cross-sectional area. Furthermore, the uniformtype are of the two kinds of aluminum alloy, namely artificially aged (T6) and naturally aged (T4). The various processes of the time history to the impact load are classified into three regions. These processes that depend on the deformation velocity are repeated the number of the crushed panels. When the absorbed energies are compared between the different aging processes, the panels of T6 excel in capacity of the absorbed energy and those of T4 excel in efficiency because the deformation for T4 increases more than that for T6. Furthermore, it is evident that the absorbed energy characteristics of the pyramidtype exceed those of the uniformtype in both efficiency and capacity.
