The open-cell Al foam was fabricated by space-holder method and Al foam-filled tube was obtained by filling Al foam into Al alloy tube. The influences of wall thickness, bonding method and filling margin on the mechanical and energy absorbing properties of Al foam-filled tubes were investigated by quasi static compression experiment. The mechanical and energy absorption properties of single and composite structures at different strain rates were studied by quasi-static compression and drop impact tests. The results show that in quasi-static compression tests, when the strain is 60%, the energy absorbed of Al foam-filled tube is 122 % of the numerical sum of Al foam and Al foam-filled tube. In the impact test, the impact load of the composite structure is more stable, and it has higher average impact load and stronger energy absorption capability. Therefore, compared with Al foam, Al foam-filled tube has a great improvement in energy absorption both in compression test and impact test.
