Porous aluminum is expected to apply as multifunctional material in various industrial fields because of a very lightweight material with high energy absorptivity. In this study, by using friction stir processing (FSP) route, the porous aluminum/dense steel sandwich panel was manufactured. In the FSP route, both mixing a blowing agent into aluminum and bonding the aluminum precursor to dense steel plate can be conducted simultaneously. It was shown that the sandwich panel of porous aluminum/dense steel which have high interface strength with high porosity of 80% and comparatively good pore structure is successfully manufactured by optimizing the foaming condition.
