The aluminium foams are a new class of materials which combines the properties derived from the cellular structure, in particular the lightness, with the typical behaviour of metals. This characteristic makes them very promising as filler material of automotive hollow body parts for dynamic (crash) and static (stiffness) behaviour improvement. Both of these features were evaluated experimantally by drop hammer tests and static bending tests respectively. The crash behaviour of simple shape profiles, designed to be representative of vehicle front members, and real components were studied; a methodology was defined for measuring energy absorbing efficiency, load-dosplacement curves at different rates by drop hammer tests in order to evaluate the foam contribution to the crash behaviour. Moreover static bending tests were performed in order to evaluate the contribution of Al-foam to the bending stiffness of foamed profiles. The good results obtained make the AL-foam a very promising material as filler of hollow structures for improving both the strength of the rigid passenger cell and the collapse behaviour of the crushable zone.
