The invention relates to a metal-based yaw brake block for a wind-powdered generator and a manufacture method thereof. The materials comprise iron powder, copper powder, tin powder, sulfur, chopped steel fiber, copper fiber, high-alumina ceramic fiber, inorganic oxides, graphite, and the like. The manufacture method comprises the following steps of: firstly, weighting all the component materials according to a prescription; stirring and mixing in a special dry-type mixer to fully and evenly disperse all the fibers; pressing and molding at room temperature; then, sintering at a certain pressure and temperature; cooling in a furnace; and finally, mechanically processing to obtain a material of the invention. Compared with a common metallurgic brake block, the friction material prepared by the method remarkably improves the mechanical properties and the static friction torque of the materials by adding metal and ceramic fibers. Meanwhile, the product has the advantages of suitable and stable dynamic friction coefficient, better wear resistance, smaller dual wear and low manufacture cost and can fully satisfy the yaw brake requirement of a wind-powdered generator.
