Abstract
A cylindrical ring-shaped friction disc contains a support body, at least one friction layer, and in each case an intermediate layer arranged between the support body and the friction layer. The intermediate layer has mutually adjoining flat regions with different coefficients of thermal expansion. A method teaches how to produce such a friction disc, and to the use the friction disc as parts of brake and clutch systems, in particular for motor vehicles.
