Abstract: An electrode connection includes coated contact surfaces in differently constructed electrode strings formed of carbon and graphite being provided with sliding layers. With the aid of these sliding layers, the elements of a string can be screwed more firmly against one another, with the result that a higher release torque and higher operating reliability are achieved.

Abstract: Fiber-reinforced ceramic composites contain bundles, tows or hanks of long fibers, wherein the long fiber bundles, tows or hanks are completely surrounded by a short fiber-reinforced matrix, with the long and short fibers having, independently of one another, a mean diameter of from 4 to 12 &mgr;m and the long fibers having a mean length of at least 50 mm and the short fibers having a mean length of not more than 40 mm, a process for producing them and their use for producing clutch disks or brake disks.
