The sandwich panels made up of AZ31 magnesium alloy sheet with the AZ31 magnesium alloy honeycomb core and AZ31 magnesium alloy sheet with the magnesium-aluminum honeycomb core were prepared respectively. Their sound insulation properties for different structural parameters of the honeycomb cores were measured. It is expected that the vibration and noise of the floor or wall of the vehicles can be greatly reduced if these honeycomb panels are applied, the riding comfort can be greatly improved and the energy efficiency can be raised. So, these panels have practical significance in transportation engineering.
