Abstract
Method for manufacturing a friction disk including preparing a mixture including a carbide-forming element having an average particle size ≦2,000 μm, a resin, optionally a binder, and optionally fine carbon, and/or short carbon fibers; forming the mixture at ≦ to 280° C. to produce a molded body; heating the molded body to approximately 750° C. to approximately 1300° C. to form a porous carbon body including a carbon residue; heating the porous carbon body to a temperature above the melting point of the carbide-forming element thereby reacting the carbide-forming element with at least a portion of the carbon residue to yield an alveolar structure; infiltrating the alveolar structure with silicon at a temperature above the melting point of silicon thereby filling at least one pore of the alveolar structure with silicon and reacting the silicon with an amount of unreacted carbon residue to form silicon carbide; and obtaining a friction disk.
