Porous aluminum is a multifunctional material with ultra light weight and high energy absorption properties. In our past study, pure Al dense pipe were fabricated and combining it with ADC12 porous Al by applying friction welding. Precursor of ADC12 porous Al was fabricated by adding blowing agent powder into ADC12 plates by means of applying friction stir processing. The precursor was put into the fabricated pure Al pipe, and the rotating tool was pressed into the precursor. Friction heat was generated and ADC12 precursor / pure Al dense pipe composite materials were fabricated by friction welding. It was shown that metal bonding between porous Al and pure Al pipe of the composites can be realized. In this study, ADC12 porous Al / pure Al bilayer pipe were fabricated to combine ADC12 porous Al to the outside of pure Al pipe by applying friction welding. The specimen with porosity of 74.5 % was successfully fabricated.
