Fabrication of the new composite materials with improved mechanical characteristics is of high interest nowadays. Simulation methods can considerably improve understanding of the interaction between the graphene and metal phase, even in the atomistic level. In the present work, the simulation of graphene-metal composites by molecular dynamics is reviewed. Both experiments and simulation results have shown that the metal matrix can be reinforced with graphene flakes, and the overall mechanical properties of the final composite structure can be significantly improved. Two basic types of metal-graphene composite structures are considered: (i) metal matrix strengthens by graphene flakes and (ii) crumpled graphene (the porous structure that consists of crumpled graphene flakes connected by van der Waals forces) as the matrix for metal nanoparticles. Several different types of interatomic potentials like pairwise Lennard-Jones or Morse or complex bond order potentials for the description of metal-carbon interaction are presented and discussed. It is shown that even simple interatomic potentials can be effectively used for the molecular dynamics simulation of graphene-metal composites. Particular attention is paid to graphene-Ni composites obtained by deformation and heat treatment from crumpled graphene with pores filled with Ni nanoparticles. It is shown, that high-temperature compression can be effectively used for the fabrication of the graphene-Ni composite with improved mechanical properties.

“…For instance, Zhang et al, compared the effect of CNTs’ addition with the effect of graphite addition on the mechanical properties of laser aided AM Inconel 625 nanocomposites [138]. In another work, Lin et al, produced a MMNCs reinforced by graphene via a hybrid manufacturing process, including layer-wise deposition of metal/graphene, followed by laser shock peening [31]. In general, the AM processes are recognized as better alternatives for the conventional production processes of MMNCs and in the future, will be one of the hot topics in this filed, and consequently, the number of publications on this topic will significantly increase [137,138,139,140].…”

Two-dimensional graphene plateletes with unique mechanical, electrical and thermo-physical properties could attract more attention for their employed as reinforcements in the production of new metal matrix nanocomposites (MMNCs), due to superior characteristics, such as being lightweight, high strength and high performance. Over the last years, due to the rapid advances of nanotechnology, increasing demand for the development of advanced MMNCs for various applications, such as structural engineering and functional device applications, has been generated. The purpose of this work is to review recent research into the development in the powder-based production, property characterization and application of magnesium, aluminum, copper, nickel, titanium and iron matrix nanocomposites reinforced with graphene. These include a comparison between the properties of graphene and another well-known carbonaceous reinforcement (carbon nanotube), following by powder-based processing strategies of MMNCs above, their mechanical and tribological properties and their electrical and thermal conductivities. The effects of graphene distribution in the metal matrices and the types of interfacial bonding are also discussed. Fundamentals and the structure–property relationship of such novel nanocomposites have also been discussed and reported.
