The invention discloses a graphene enhanced aluminum-based light brake disc and a preparing method thereof. In the material, the characters of heat conductivity and abrasion resistance of graphene areutilized, and abrasion resistance and heat conductivity of the aluminum-based brake disc made of the material are improved. The surface of the graphene is sequentially wrapped by a heat conductive silicon carbide layer and an abrasion resisting zirconium oxide layer, and running stability and abrasion resisting performance of the graphene in the aluminum-based brake disc can be further improved.The graphene enhanced brake disc material has good hardness, abrasion resistance and heat conductivity.
