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.

Sintered, carbon friction material made from fibrous materials that are impregnated with resin prior to sintering wherein the sintered material has an more open porosity than original.
Sintered, carbon friction material made from fibrous materials that are impregnated with resin prior to sintering wherein the sintered material is a sintered, porous carbon body having a macro porosity.
A method of manufacturing sintered, carbon friction material including the steps of:
- impregnating fibrous material with a resin before sintering;
- sintering the resin impregnated fibrous material at a temperature ranging from 400 to 800° C.;
- and
- producing a sintered, carbon friction material, wherein the sintered material has an open porosity above 50 percent by volume.
