Aluminum foam composite of aluminum alloy die casting ADC12 core coated by pure aluminum A1050 was fabricated. In the fabrication method, after an A1050 precursor was foamed in an electric furnace, an ADC12 precursor was foamed in the A1050 foam using optical foaming. The pore structures of the fabricated aluminum foam composite were examined using X-ray computed tomography (CT) inspection. Moreover, it was shown that the bonding condition between ADC12 and A1050 regions can be improved. Next, static compression tests of the aluminum foam composite was carried out. Based on these test and inspection results, it was shown that the plateau stress can be evaluated approximately within ±20% error by using mean compressive stress on a maximum-porosity cross section perpendicular to the direction of compressive loading.
