Abstract
A friction material has a plurality of connected sections defined by a plurality of notches therebetween. Each notch has an apex which compensates for tear and compression of the friction material when the friction material is circumferentially placed on a flat surface of an annular core plate. In certain embodiments, a multiple linked loading device places the notched friction material adjacent a core plate to form a clutch plate.
