Due to graphene unique two-dimensional structure and excellent mechanical, thermal and electrical properties, graphene had attracted wide attention in recent years. Therefore, graphene was used as a reinforcing material in aluminum matrix composites. The main research directions and progress, preparation methods and technology of graphene/aluminum matrix composites, and the mechanism of graphene strengthening were reviewed. The interface reaction, the competition mechanism between Al31Vlg2 and SiC and brittle phase AL4C3, and the dispersion of graphene in aluminum matrix were discussed. The development direction of graphene-reinforced aluminum matrix composites is prospected, which provides a reference for the research and application of new graphene/aluminum matrix composites.
