Sažetak
Aluminium foam is, principally, a composite material consisting of aluminium or aluminium alloy matrix and of pores filled up with a gas distributed throughout the matrix. This paper studies the reproducibility of aluminium foams energy absorption efficiency. Samples of aluminium foam were produced from an Alulight precursor (AlMgSi0.6 TiH2-0.4). This precursor was placed into a mould form and heated up until the agent starts to foam. Immediately thereafter the mould is taken out of the furnace and cooled off, so the aluminium foam part is frozen in shape. The ability of samples to absorb mechanical energy was estimated from the results of compression tests. Tests were carried out by a universal test machine. Test results showed that aluminium foams have good energy absorption efficiency and repeatability is relatively low.
