Closed cell Al/SiCp composite foams are typically manufactured via casting method. The composite foams are made from aluminum foam into which SiCp is added at different concentrations (5, 10, 15 vol%). Effects of SiC particles on compressive and fatigue behaviors of composite foams were investigated. Results showed that, yield stress of the composite foams increases with increasing the strain rate. The yield stress and fatigue strength of samples of Al/SiCp composite foam containing SiCp at different concentrations increased with increasing the SiCp volume fraction up to 10 vol%. Based on the results, compressive strength of the foam sample containing 10 vol% SiCp with a density of 0.58 g cm−3 was higher than other samples. On the other hand, the lowest compressive strength was found to be that of the foam containing 5 vol% SiCp due to less than enough content of foam stabilizer in this foam. Moreover, at a given SiCp content, an increase in foam density increased the fatigue strength.
