NOVELTY - The preparation method of composite material involves adding aluminum powder to copper powder and then mixing, ball milling the mixture, adding 1 wt.% stearic acid as process control agent, carbon source and anhydrous dextrose to the mixture and then dissolving in ethanol solution, heating the mixture and then calcining, adding graphene to the mixture and then sintering, heating the mixture, and rolling. USE - The method is useful for preparation of composite material (claimed). ADVANTAGE - The method enables preparation of composite material with excellent tensile properties and toughness.
