Beschreibung
Zusammenfassung:	PURPOSE:To obtain a frictional surface material for a brake and a clutch having improved frictional wear characteristics and shock resistance by combining a carbon fiber reinforced carbon composite material with semicarbon. CONSTITUTION:A thermosetting resin compsn. is impregnated into a carbon fiber reinforced carbon composite material having 5-30% porosity. After heat curing, the composite material is heat-treated to convert the compsn. into semicarbon by cyclization-dehydrogenation.
