Developments in aluminium alloy composite materials

Research output: Contribution to journalArticleResearchpeer-review


One method for meeting the demands for improvements in the properties of engineering materials is the practice of combining different materials to form composites, with properties superior to those of the components. Laminates or sandwich panels, and more recently, metals reinforced with fibers or particulates are examples in which special attention has been given to materials based on aluminium. Properties of particular interest are specific stiffness, strength at elevated temperatures and wear resistance. Many of these materials are experimental or at an early stage of commercial development and all involve cost premiums which may be substantial when compared with alloys produced by conventional ingot metallurgy. Some of these developments are reviewed and their potential impact on light alloy metallurgy are analyzed.
