摘要: Abstract In this study, open cell Al–Al2O3 composite foams having different volume fractions of Al2O3 (0–10 vol.%) were synthesized by using the space-holder technique. Various amounts spherical carbamide particles with mean size 1.2 mm used for producing porosity 50, 60 and 70 vol.%. Compression test was performed on foam samples evaluating compressive properties energy absorption behavior them. The results showed that depend fraction fraction. Generally, decreasing fraction, capacity raised. containing 2 vol.% superior in contrast to other studied work. Also it found, as strain during compression is increased, increased too. It noticeable that, slope capacity–strain curves decreases increasing
