The honeycomb aluminum foam of the porous metal has the merit of the impact absorption, thesoundproof, the heat conductivity, the light weight. Aluminum 6061-T6 is used at the materials for theautomobile, the ship, the machine and various structures. In this study, the sandwich combined with thehoneycomb aluminum foam and aluminum 6061-T6 is simulated with the impact. Two kinds of modelsmade by use of CATIA program with 3 kinds of impact energies are analyzed by ANSYS program. Asthe simulation result, the maximum deformations at the cases of 1 and 2 are shown as 4.8205mm and11.909mm respectively. And the maximum equivalent stresses at the cases of 1 and 2 are shown as274.45MPa and 265.6MPa respectively. As the simulation result at case 1 approaches the experimentalresult, all simulation results can be verified in order to apply into analyzing the impact properties of thehoneycomb aluminum foam sandwiches. In cases of three kinds of impact energies, the striker is notshown to penetrate the upper face sheets of case 1. At the impact energy of 100 J, the striker is notshown to penetrate the upper face sheets of case 2. At the impact energies of 200 J and 300 J, thestriker is shown to penetrate the upper face sheets of case 2. It is thought to predict and improve thestructural safety the composite material combined with the aluminium foam by using this study result.
