Abstract

This research work investigates the mechanical properties of two distinct novel composites of aluminum foam made from the addition of recycled ballistic aggregates to the foams of aluminum alloy powder in regular and random patterns through powder metallurgy process. The mechanical attributes of these composites were examined in compression loading using digital image correlation (DIC) and compared to baseline properties of steel and aluminum foams obtained in the laboratory and literature respectively. The results obtained for aluminum foam ceramic composite made through the dispersion of ceramic aggregates in regular orientation showed an increase in its plateau stress, yield strength, strength/density ratio and relative density, but a decrease in its modulus of elasticity was observed. This observation was similar to the composite with a random arrangement of ceramic aggregates, except for a decrease noticed in its yield strength and elastic modulus.
