Abstract

Fiber-reinforced ceramic composites which comprise at least two layers of a multidirectional woven fiber fabric as reinforcement, with at least 5% of the area of each layer of woven fiber fabric being permeated by matrix material, friction disks comprising these composites as core zone or support zone, a process for producing them and their use as brake disks or clutch disks.
