Abstract

The invention discloses a damping wear-resistant steel material and a preparation method thereof. In the damping wear-resistant steel material, damping wear-resistant steel serves as a matrix; steel wire rolls and carbon fibers are distributed in the matrix; the diameter of each steel wire roll is 10 to 15 centimeters; each steel wire has a rectangular section and the section size is 0.1-0.4 mm*0.5-1.5 mm; the weight ratio of the steel wires to the carbon fibers is 25-30:1; and the steel wires and the carbon fibers account for 20 to 40 percent of the volume of the material. The damping wear-resistant steel material prepared by the method has high toughness and wear resistance, a simple process and low production cost.
