The present disclosure relates to a fiber-reinforced copper-based brake pad for high-speed railway train, and preparation and friction braking performance thereof. The fiber-reinforced copper-based brake pad for high-speed railway train comprises 80-98.5 wt. % metal powder, 1-15 wt. % non-metal powder and 0.5-5 wt. % fiber component. In addition, some components are added in a specific proportion to achieve optimal performance. The copper-based powder metallurgy brake pad is obtained by powder mixing, cold-pressing and sintering with constant pressure. The friction braking performance of the obtained brake pad is tested according to a braking procedure consisting of three stages, i.e., the first stage with low-pressure and low-speed, the second stage with high-pressure high-speed and the continuous emergency braking third stage with high-pressure and high-speed. The brake pad has advantages including higher and more stable friction coefficient, higher fade and wear resistance and slighter damage to brake disc at high speeds.
