In this study, open cell Al–Al 2 O 3 composite foams having different volume fractions of Al 2 O 3 (0–10vol.%) were synthesized by using the space-holder technique. Various amounts of spherical carbamide particles with mean size of 1.2mm were used for producing porosity fractions of 50, 60 and 70vol.%. Compression test was performed on the foam samples for evaluating the compressive properties and energy absorption behavior of them. The results showed that the compressive properties and energy absorption behavior depend on the volume fraction of Al 2 O 3 and porosity fraction. Generally, by decreasing the porosity fraction, the energy absorption capacity and compressive properties were raised. The composite foams containing 2vol.% Al 2 O 3 showed superior compressive properties and energy absorption behavior in contrast to other foams studied in this work. Also it was found, as the strain during the compression test is increased, the energy absorption capacity is increased too. It is noticeable that, the slope of energy absorption capacity–strain curves decreases by increasing the porosity fraction.
