PRODUCTION OF ALUMINIUM FOAM AND THE EFFECT OF CALCIUM CARBONATE AS A FOAMING AGENT

Abstract

Metallic foams are gaining ground as important new engineering materials.Aluminium foams were produced with different densities using different percentages of calcium carbonate as a foaming agent. The mechanical properties of the foamed material were tested using uniaxial-compression test. Plateau stress σpl, densification strain εd and energy absorption capacity U, were calculated. The obtained results show that the collapse strength and the absorbed energy of foams increase with increasing the density.
