Abstract
Porous aluminum (Al) is a lightweight with high energy absorption properties and expected as structural materials. In this study, static compression tests of porous Al core filled in SUS304 pipe composite material (porous core pipe) with slits fabricated by friction welding were carried out. Precursor of porous Al was fabricated by friction stir processing (FSP) route. Precursor was put into the SUS304 pipe, and rotating tool was pressed into the precursor. Then,, bonding between Al precursor and SUS304 pipe can be conducted. The slit parts are formed by notching the porous core pipe. From the compression tests, it was suggested that the slits are effective to control the compressive deformation behavior.
