In this study, porous aluminum core filled in hollow thin-walled steel pipe composite materials (porous core pipe) was fabricated by applying friction welding. Precursor of ADC12 porous A1 was fabricated by adding blowing agent powder into ADC 12 plates by means of applying friction stir processing. The precursor was put into the hollow thin-walled steel pipe, and the rotating tool was pressed into the precursor. Friction heat was generated and ADC12 precursor / SUS304 thin-walled steel pipe composite materials were fabricated by friction welding. Porous core pipe with metal bonding was successfully fabricated by heating the precursor. The compression properties and deformation behavior of porous core pipe was obtained by the compression test. As a result, deformation behavior of porous core pipe was different from the hollow pipe and compressive stress of porous core pipe increased compare with the hollow thin-walled steel pipe and ADC 12 porous Al.
