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.
