The invention discloses a powder metallurgy brake pad for a D-series high-speed train set. The powder metallurgy brake pad comprises a steel backboard, a dovetail block and a plurality of brake pad friction bodies. The steel backboard and the dovetail block are of an integrated forming structure, any brake pad friction body is fixed to the steel backboard through a big gasket and a rivet, each big gasket is located between the corresponding brake pad friction body and the steel backboard, and the positions, located on the edges of the brake pad friction bodies, of the steel backboard are provided with flanges matched with the brake pad friction bodies in shape. According to the brake pad, due to adoption of the structure of particular design, rigidity and reliability of the steel backboard are increased, the machining process and riveting process are simplified, the production cost of the brake pad is lowered, reliability of the brake pad is improved, the service life of the brake pad is prolonged, and the powder metallurgy brake pad can be widely applied to brake systems of various railway vehicles and high-speed D-series train sets.
