Abstract
A friction facing for clutches and the like of improved hot burst strength formed of a glass fiber tape disposed in an undulating annular fashion, the undulations being compressed and bonded together by a heat-curable cement system containing rubber, resin and friction modifiers, the rubber being a vulcanizable carboxy nitrile rubber, the resin being a water-soluble, low molecular weight, one-step thermosetting phenol formaldehyde resin, and the friction modifiers being finely divided organic and inorganic particles. In fabricating the friction facings, prior to the application of the heat-curable cement system, there is applied to the glass filaments a precoating comprising rubber, resin and furnace black which is compatible with the cement system and which is applied as an aqueous dispersion.
