Graphene materials with excellent mechanical and physical properties as well as two-dimensional flexible morphology are attractive reinforcement nanofillers for aluminum matrix nanocomposites. Rapid progress in graphene materials and nanocomposites fabricating technology promotes the development of advanced graphene-reinforced aluminum matrix nanocomposites for structural and functional applications. Nevertheless, the dispersion of graphene nanofillers within aluminum matrix and the interfacial controlling between them remain long-standing challenges in the fabrication of graphene-reinforced aluminum matrix nanocomposites. This article focuses on the recent development of the fabrication and characterization of graphene-reinforced aluminum matrix nanocomposites, including the dispersion and consolidation technology of graphene-reinforced aluminum matrix nanocomposites as well as their structural characters and mechanical behaviors.

Matrix Nanocomposites

Aluminum based composites find diverse applications due to their superior mechanical and physical properties. Aluminum matrix nanocomposites have been synthesized with Al3Fe nanocrystalline intermetallics reinforcement using the powder metallurgy route. The prepared composites have been characterized for various physical and mechanical properties such as density measurement, bulk hardness, compressive strength, and tribological properties. The theoretical coefficient of the linear thermal expansion has also been predicted. The composite shows a high strength to weight ratio and excellent wear resistance, along with a low coefficient of friction. The observed wear rate is superior to other composites irrespective of the load and sliding velocity chosen for the study and it continuously decreases withan increasing amount of dispersoid.
