Abstract
SiC particle reinforced AlCu5Mn composite foams (SiCp/ZAlCu5Mn composite foams) were fabricated by the direct foaming of the melt. The quasi-static compressive properties of SiCp/ZAlCu5Mn composite foams were tested by compressive test. The effects of SiC particle, the average diameter of pores, and the relative density on the quasi-static compressive properties of SiCp/ZAlCu5Mn composite foams were performed with the universal material testing machine. The microstructure of SiCp/ZAlCu5Mn composite was studied by SEM. The results show that choosing small size of SiC particles as reinforced material, thinning pore diameter, and increasing the relative density of SiCp/ZAlCu5Mn composite foams with the same volume fraction of SiC particles can improve the energy absorption ability under the quasi-static loading. SiCp/ZAlCu5Mn composite foams are of well compressive property. The compressive deformation course of SiCp/ZAlCu5Mn composite foams involves three stages that are the linearly elastic deformation region, the collapse plateau region, and the densification region. The test results may be influenced by strain gauge, data processing method, shape of incident wave etc.
