Basic science of graphene with various superior characteristics has been made clear rapidly on the frontier technology. We focused on graphene/Al nano composite materials. Since our original successful isolation techniques of creating single layer nanographene sheets from nanographene with a several sheet and uniforming dispersion of nanographene within based materials, we have been challenging in fabrication innovative graphene reinforced Al composite sintered materials with high specific strength and established the fabrication method. It has already been demonstrated that graphene/Al nano composite materials give us excellent possibility of the innovative industrial use materials with a promising future. In this study, we investigated possibility that tribological properties of our graphene/Al nano composite materials. Friction coefficient and wear properties were analyzed. Friction coefficient showed that in the case of that opposite material is SUJ2 the composite material showed improvement up to 67%, and the wear amount of the composite material also improvement up to 98%. In the case of material of alumina friction coefficient also showed that the composite material showed improvement up to 27%, and the wear amount of the composite material improvement up to 89 %. Therefore, we demonstrated effectiveness that tribological properties of our graphene/Al nano composite materials.
