Original paper friction materials were energy limited and their use confined to light duty vehicles. Recent innovations in paper friction material compositions now permit consideration of this type of friction facing for all wet friction applications. A comparison of the properties of these new materials with those of traditional paper friction compositions, demonstrates the attractive features of the new materials. New friction paper compositions allow the potential user to select desired properties from a wide range of performance characteristics. The installation of an automated paper friction clutch disc production line further enhances the reliability and cost-effectiveness of paper friction materials.
