<p>The cylindrical ring-shaped friction disc comprises a support body and a friction layer, where an intermediate layer is arranged between the support body and friction layer. The intermediate layer has mutually adjoining flat regions with different coefficients of thermal expansion. The difference in the thermal expansion of flat regions lies with different thermal expansion of 10% of the higher value for the linear thermal expansion coefficient. The regions in the intermediate layer exhibit dimensions in the plane parallel to a bottom surface or a top surface of the disc of 0.5-10 mm. An independent claim is included for a method of preparing a cylindrical ring-shaped friction disc.</p> |
