By using sandwiches with an aluminum-foam core, it is possible to obtain a higher stiffness and rigidity, maintaining stability against buckling and additionally making use of the high energy dissipation capability of the foams. A recent highlight in lightweight construction is the use of aluminum-foam sandwiches (AFSs) in space-frame constructions.en620660671journal article
