Performance Characteristics of a Non-Asbestos cellulose Fiber composite Friction Material

Dynamometer performance characteristics are presented on S. K. Wellman N-266, a non-asbestos cellulose fiber composite “paper type” friction material for oil-cooled clutches and brakes. Friction characteristics, energy capacity, and endurance under a variety of test parameters are discussed. Relationships between key frictional operating parameters and material density variations are also analyzed.
