【Abstract】 Metal matrix composites(MMCs), especially aluminum matrix composites(AMCs), are widely used in the applications of aerospace, automotive, mechatronics and other areas due to the advantages of high specific strength, high specific modulus, and excellent thermal and electrical conductivity. In recent years, carbon nanomaterials as the reinforcement of MMCs, have attracted great attention for their outstanding mechanical and functional properties. This review focuses on the progress on preparation methods and mechanical properties of different dimensional carbon nanomaterials(0-D carbon nano-onions, 1-D carbon nanotubes, 2-D graphene et al.) reinforced AMCs. The design ideas of aluminum matrix composites with high strength and toughness through the structural construction have been summarized ranging from single-to multi-dimensional hybrid reinforcements, and the future research trends of MMCs have been prospected.更多还原
