Abstract
A friction disc paddle for a rotatable clutch disc has powdered metal friction faces compacted directly on each face of a metal substrate. The friction faces extend through apertures in the metal substrate, and extend to the circumferential and radial edges of the metal substrate. The friction faces are solidly bonded to the metal substrate. The apertures not only ensure that the friction faces are securely attached to the metal substrate, but they also reduce the overall weight of the friction disc paddle.
