Since its discovery, graphene has become an ideal reinforcement material for aluminum matrix composites due to its unique performance advantages. With the development of the research on graphene reinforced aluminum matrix composites, more and more preparation technologies and methods have been found. Meanwhile, the existing problems are also revealed one by one, such as reinforcement agglomeration, poor interfacial bonding and severe interface reactions, and so on. All these problems can seriously affect the final performances of aluminum matrix composites and restrict the development of graphene reinforced aluminum matrix composites. In this paper, the current research status of graphene reinforced aluminum matrix composites at home and abroad were summarized, elaborates the selection among reinforced graphene oxide, reduced graphene oxide and graphene nanosheets, and the preparation method of graphene reinforced aluminum matrix composites were introduced. In addition, the interfacial issue between graphene and aluminum matrix and the directional alignment of graphene in the matrix were analyzed. Finally, the future research direction of graphene reinforced aluminum matrix composites was briefly expounded.
