Abstract
A graphene reinforced aluminum matrix composite with high electrical conductivity and a preparation method thereof. The method includes: obtaining aluminum coated graphene powder by plating aluminum on a graphene surface, melting aluminum block into aluminum liquid, heating a mold to be lower than an aluminum melting point, alternately pouring the aluminum liquid and the aluminum coated graphene powder into the mold for layered casting to obtain a sandwich structure; extruding the sandwich structure into a rectangular test block and then heating to 500˜600° C., performing heat preservation for a preset time and performing forging treatment, and performing longitudinal cold deformation under inert gas to obtain the graphene reinforced aluminum matrix composite. The method can solve a problem that poor wettability of graphene and aluminum matrix, the graphene is evenly dispersed in the aluminum matrix, which can improve strength of the aluminum matrix and keep its high electrical conductivity.
