Aluminum foams are an attractive material which can reduce the car weight and can improve the rigidity of a car and the energy absorption in a car collision. In this study, to apply the foams to car-parts like a B-pillar and a bonnet, the bending property of the foams and possibility of the fabrication of car-parts by bending are examined. To improve the bending limit of aluminum foams which have a weak point for the tensile deformation, experiments with a warm working and with various radii of bending jig and FEM analysis of sandwich structures are carried out.
