Research progress on preparation technology and strengthening mechanism of graphene reinforced aluminum matrix composites

Abstract

Graphene has become one of the ideal reinforcers for aluminum matrix composites due to its unique structural characteristics and excellent properties. This paper mainly introduces the preparation technology of three categories of graphene-reinforced aluminum matrix composites, including the liquid forming method, powder forming method and composite processing technology, and so on. Base on analyzing the principle of different types of preparation technology, combined with four strengthening mechanisms of graphene-reinforced aluminum matrix composites, the development trend of graphene reinforced aluminum matrix composites is prospected, including the basic theoretical research, the breakthrough of preparation technology and large-scale industrial application of composites.
