抄録

Porous aluminum (Al) is a lightweight with high energy absorption properties and expected as structural materials In this study, porous Al core filled m Al pipe composite materials was fabricated by friction welding Precursor of porous Al was fabricated by mixing the Al plates and blowing agent powder by friction stir welding route Obtained precursor was put into the Al pipe, and rotating tool was pressed into the precursor Then, bonding Al precursor to Al pipe can be conducted by mean of plastic flow Porous Al core filled in Al pipe composite materials with metal bonding was successfully fabricated by heating the precursor By using X-ray CT, pore structure of inside porous Al was observed
