This invention discloses a copper-based powder metallurgy friction plate for wind turbine torque limiters and its preparation method. The friction plate blank is first subjected to pressureless sintering to obtain a pre-sintered blank, and then the pre-sintered blank is re-pressed to obtain a re-pressed friction plate blank. The re-pressed friction plate blank is then assembled with a copper-plated steel backing to obtain a composite blank, which is then subjected to pressure limiting sintering to obtain the final product. The preparation method of this invention, through the synergy of pressureless pre-sintering, re-pressing, and pressure limiting sintering, obtains a copper-based powder metallurgy friction plate for wind turbine torque limiters with small deformation, high density, and excellent mechanical and tribological properties.
