The invention provides a metal matrix composite material, which uses metal as a matrix and uses graphene modified on the surface of carbide as a reinforcement. Due to the surface modification of the carbide, the interface bonding strength between the metal matrix and the graphene can be adjusted. For example, when the chemical affinity between graphene and the metal matrix is ​​too strong and an excessive reaction occurs, resulting in an excessively strong interface bond, the carbide can be used as a diffusion barrier to avoid the overreaction and weaken the interface bond; When the interfacial affinity is weak, the carbide can be used as a transition layer to promote interfacial wetting and improve interfacial bonding force.
