Pantograph carbon contact strip preform with communication pores obtained based on three-dimensional bionic technical approach with graphene and fiber as raw materials so as to improve conductivity of a carbon contact strip. By immersing the pantograph carbon contact strip by a metal melt of brazing filler metal and copper, three materials, i.e. copper, brazing filler metal and carbon can be closely combined together so as to improve an interface combination force of copper and carbon. During the immersion, a strong magnetic field is externally applied to drive the copper alloy liquid to diffuse in the pores of the pantograph carbon contact strip preform, thereby improving immersion efficiency and further increasing a mechanical strength and an arc ablation resistance of the carbon contact strip. The present disclosure is capable of effectively solving the problems of low conductivity, low mechanical strength and poor arc ablation resistance of the pantograph carbon contact strip.
