Industrialization of powder compact foaming process

The potential for applying metal foams in lightweight construction is mainl y based on the increased stiffness of two flat or curved sheets that are se parated by a foam layer as compared to a single sheet of the weight. By usi ng sandwiches with an aluminum-foam core, it is possible to obtain a higher stiffness rigidity maintaining stability against buckling and additionally working use of the high dissipation capability of the foams. A recent high light in lightweight classification is thp use of aluminium-foam sandwiches (AFSs) Zn space-frame constructions.
