Porous aluminum has lightweight and high energy absorption properties. In this study, impact test of functionally graded porous aluminum by varying pore structures was carried out. Functionally graded porous aluminum was manufactured by heating the precursor that was made by precursor without a blowing agent addition and with a blowing agent addition. It was shown that deformation of functionally graded porous aluminum changed from the high porosity layer to the low porosity layer. This result shows that functionally graded porous aluminum has two characteristics of a low porosity layer and a high porosity layer under the compression.
