▎ 摘　　要

NOVELTY - Graphene of high-speed train braking brake sheet material comprises a matrix component, a matrix reinforcement component, a friction component and a lubricating component. The sum of the mass percentage content of each component is 100%. The base component is copper powder, the copper powder is atomized copper powder or electrolytic copper powder. The mass percentage of copper powder atomized is 45-70%. The matrix reinforcement is composed of graphene oxide and iron powder, or composed of iron oxide and ferric oxide. The iron powder is reduced iron powder. USE - Graphene of high speed train braking brake sheet material used in high-speed train braking shoe plate. Can also be used in brake disc and brake disc. ADVANTAGE - The brake sheet material has high strength, good high temperature resistance and good wear characteristics, and satisfies the brake requirement of the high-speed train at the speed of more than 350 kilometers per hour and above. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of the graphene of high speed train braking sheet material.
