Abstract
Sintered, carbon friction materials are made from fibrous materials that are impregnated with resins prior to sintering. Preferably, non-woven fibrous materials are impregnated with phenolic resin and sintered at 400 to 8000 C. The resulting material has an open porosity above 50 percent by volume.
