Abstract

This paper presents an overview of stabilized aluminum foams (SAF). The main objectives are the evaluation and development of these materials. Metal foams are metal matrix composites (MMC) characterized by: higher specific properties, high capacity vibration damping and sound, mechanical energy absorption etc. The wide range of possible properties can lead to innovative applications, which is a strong driving force for the improvement of metal foam production technologies. Investigated and studied materials are composite of aluminum alloy matrix where the stabilization of the gas bubbles has been done by ceramic particle added. The paper also presents some manufacturing processes of SAF, (such as sheet casting, low pressure casting, precursor technology) and some SAF’s characteristic properties. Finally, the various application fields for cellular metals are discussed. They are divided into structural and functional applications and are treated according to their relevance for the different industrial sectors..

Keywords
