Abstract: In this paper, different diameters of aluminum foam elements were prepared by advanced powder compact melting method (APCM), and then it was filled into aluminum alloy thin-walled tubes in a disorderly manner according to different bonding methods, and finally different types of composite structures of APCM aluminum foam-filled thin-walled tubes were obtained (filled tubes). The quasi-static compression test of the filled tubes was carried out by a universal testing machine, and the effects of the filling diameter and the bonding method on the mechanical properties and energy-absorbing effect of the filled tubes were investigated. The results show that the bonding method has a more significant effect on the performance of the filled tubes than that of the filling element diameter. Under the same bonding method, the compression energy absorption effect of the filled tubes with a filling element diameter of 15 mm is the best; under different bonding methods, the compression energy absorption effect of the foam bonded filled tubes is the best, while the compression energy absorption effect of the bonded filled tubes is better than that of the non-bonded filled tubes.
