Porous aluminum is a porous material with pores inside. Therefore, compared to aluminum alloy, it is superior in light weight, shock ab-sorption, heat
insulation, sound absorption, etc., and it can be expected to be applied to industrial parts. Since porous aluminum has different properties depending on the
type of base material and porosity, it is possible to fabricate functionally graded porous aluminum by combining porous aluminum with different properties.
The purpose of this study is to optimize the fabrication of functionally graded porous aluminum.
