There is described a one-piece friction body having a support and at least one friction pad disposed thereon, based on friction materials containing reinforcing fibers, thermoset binders and customary additives, in which the at least one friction pad is joined to the support integrally and positive-locking by means of reinforcing fibers penetrating the boundary layer between the support and the friction pad. There is further described a method of manufacturing this friction body, comprising the steps of bonding together the friction materials containing reinforcing fibers, thermosetting binders and customary additives for the support and the at least one friction pad in the desired shape and arrangement, needling the reinforcing fibers contained in the friction materials of the composite in such manner that at least the reinforcing fibers of the friction material of the at least one friction pad penetrate at least in part the friction material of the support and of the other friction pad, respectively, and curing the needled intermediate under heat and pressure in a pressing mold corresponding to the friction body to be manufactured.
