The lightweight aluminum alloy honeycomb material has higher strength and stiffness, it can be used as sandwich board inner materials, so it is an ideal light structural material. In this paper, the SHPB technique is used for studying the dynamic mechanical response of lightweight alloy honeycomb panels whose diameter is 30mm under different high strain rate. The dynamic stress-strain curves of materials have been given, and the results and data of experiments have been analyzed. While the microscope is used for observing the cell figures which the specimens after tested to study the buffering and energy absorption ability of the material.
