Abstract

Graphene with unique two-dimensional structure and excellent mechanical properties, is one of the most ideal reinforcements. With the increasing progress of aluminum matrix composites, graphene reinforced aluminum matrix composites have attracted great interests. This paper mainly reviews the latest progress on preparation of graphene reinforced aluminum matrix composites, and especially discusses the effective dispersion technique of graphene. Meanwhile, the microstructure and interfacial structure of graphene reinforced aluminum matrix composites are also emphasized and discussed. The results showed that graphene can significantly improve the mechanical properties of composites and refine the matrix grain. By controlling preparation parameters, the graphene agglomeration can be effectively solved, and the adverse interface reaction between graphene and substrate can be avoided. Finally, the current challenges and solutions of graphene reinforced aluminum matrix composites were presented.
