Developments of discontinuously reinforced aluminium matrix composites: Solving the needs for the matrix

Abstract

Metal matrix composites become interesting for use as constructional and functional materials. The development of metal matrix composites was primarily directed to the continuous-fibre reinforced metal matrix composites - such as boron fibre/aluminium-based matrix, continuous alumina fibres /aluminium-based matrix, graphite fibre/aluminium-based matrix or graphite fibre/magnesium-based matrix composites. Despite the successful production of these metal matrix composites, they manufacturing was limited by the concerns related to the technological processes and cost, their availability remaining a significant barrier to their manufacturing. The benefits of metal matrix composites as compared to the unreinforced (monolithic) metals or alloys include superior mechanical and physical properties that deliver improved structural performance. This concept also further implies re-using materials or using recycled materials. Therefore, discontinuously reinforced metal matrix composites are suitable for a wide range of industrial applications. This study aims to investigate the developments in area of solving the needs for the matrix material necessary for the discontinuously reinforced aluminium matrix composites. Aluminium can be recycled directly back into itself over and over again in a true closed loop.
