  • High energy friction product
    Patent number: 6277769
    Abstract: A high temperature and energy capacity friction material for wet brake and clutch applications comprising a resin impregnated carbon fabric. Preferably, the fabric is a woven cloth and the resin is a thermoset such as phenolic resin. The invention involves the controlled impregnation of the fabric so as to leave the fabric with a high compressive strength, effectively impervious to internal oil flow, but with macroscopic voids between the tows of yarn to afford local reservoirs of oil at the working surface and flow of oil across the working surface.
