ABSTRACT:
A rotatable brake or clutch friction disc formed of a material having characteristic strength weakness in tension and shear modes and provided with an annular metal force transmitting member interposed between the disc and fixed or rotatable portions of the brake or clutch. The annular metal force transmitting member has a plurality of circumferentially spaced apart radially extending key engaging slots or slot engaging keys. The annular metal force transmitting member may be provided with opposite radially extending annular metal shields which slidably engage similar shields on adjacent discs to provide a barrier tending to minimize air flow to and thus oxidation of a heated friction disc.
