Abstract:
A friction product comprising a flat core sheet and friction material bonded to both sides of the core sheet, the core being formed of steel and being circular in shape, the friction material having an annular shape concentric with the center of the core, the friction material comprising a cloth fabric woven from strands made of carbon fiber and impregnated with phenolic resin, the resin being present in the fabric to impart compressive strength to the fabric by substantially reducing porosity and substantially eliminates permeability of the fabric to oil flow through the body of the fabric, but leaves sufficient voids between the tows of the fabric yarn to retain limited amounts of oil and permit limited flow of oil on and across the working surface of the friction material whereby the friction material is capable of extended cycles of energy absorption in the range of about 500 to 600 joules/cm.sup.2 without glazing or other degradation.
