Nonporous layer was fabricated on surface of closed-cell type aluminum foam (Shinko Wire Company, Ltd.: ALPORAS, relative density: 0.1, mean diameter of pore: φ4 mm) by friction stir incremental forming method. The nonporous layer with mean thickness of 240 μm was successfully fabricated under appropriate forming conditions. To examine the mechanical properties of the fabricated aluminum foam with nonporous layers, uniaxial compression test was carried out on a material testing machine at room temperature. The specific compressive stress (compressive stress/bulk density) of the fabricated aluminum foam with nonporous layers was enhanced.
