Abstract

The invention relates to a graphene and carbon nano tube enhanced aluminum matrix composite and a preparation method thereof, and belongs to the technical field of aluminum matrix composites. In orderto solve the problems that graphene and carbon nano tubes are clustered and form carbide with an aluminum matrix at a high temperature and in order to improve the wear resistance of the aluminum matrix composite, the graphene and carbon nano tube enhanced aluminum matrix composite is provided, and components of the graphene and carbon nano tube enhanced aluminum matrix composite comprise, by masspercent, 0.1%-5.0% of composite copper plated nickel graphene, 0.1%-5.0% of composite copper plated nickel carbon nano tubes, 5% of magnesium powder and the balance aluminum powder. Copper plated nickel is compounded on the surfaces of the graphene and the carbon nano tubes to strictly control the interface reaction, ultrasonic dispersion is carried out in a stirring state so that the graphene and the carbon nano tubes can be evenly dispersed in the aluminum matrix composite, finally the enhanced aluminum matrix composite is obtained through vacuum hot-pressing sintering, and the wear resistance of the aluminum matrix composite is obviously improved due to the self-lubricating characteristic of the graphene and the carbon nano tubes.

Description

technical field [0001] The invention belongs to the technical field of aluminum-based composite materials, and in particular relates to a graphene and carbon nanotube reinforced aluminum-based composite material and a preparation method thereof. Background technique [0002] Aluminum alloys have low density and excellent machinability, and are widely used in aviation, aerospace, automotive and electronics industries. However, with the rapid development of modern industry, aluminum alloy materials have been unable to meet the performance needs of industrial development in many aspects. Combining aluminum with other materials to prepare aluminum matrix composites is one of the most important ways to improve the comprehensive mechanical properties of aluminum alloy materials. Carbon fiber can effectively enhance the strength and stiffness of aluminum alloys. Therefore, carbon fiber aluminum matrix composites have received sufficient attention and gradually realized their appli...
