Method for producing friction disks, comprising a supporting body and at least one friction layer, characterised in that the at least one friction layer is produced from a silicon carbide slurry which additionally contains phenolic resin dissolved in a solvent and a mass proportion in the solid material of the slurry from 0.1% to 10% of fibres or fibre bundles made from carbon, wherein the friction layer produced from this slurry is attached to a supporting body, which is present in the form of a cylinder ring in the CFRP state, a) is attached to the supporting body in the CFRP state by spraying, scraping, pouring, spreading or rolling of the slurry, and the firmly-adhering, flat layer resulting after the drying at 20°C to 60°C is cured by heating to a temperature from 120°C to 280°C, or b) as a preform produced from the slurry, wherein a film is poured from the slurry from which friction disks are stamped after drying to a leather-like flat structure, and these are cured into a friction disk in the CFRP state by heating to a temperature from 120°C to 280°C, or c) as a preform in friction disk-form produced from the slurry according to the slurry casting method, wherein a mould made from a porous, water-absorbing material is provided into which the slurry is filled, and wherein after the delivery of the dispersing agent in the mould, a dry preform is extracted from this, which is cured into a friction disk in the CFRP state at a temperature from 120°C to 280°C, or d) as a friction disk which is injection moulded from the slurry after pre-draining, thickening and plasticising, wherein - the slurry is firstly pre-drained and thereby thickened, then - the pre-drained, thickened slurry is plasticised by heating and - injection-moulded into a friction disk, which is cured into a friction disk in the CFRP state in a separate step by heating to a temperature from 120°C to 280°C, and is then carbonised and siliconized together with the supporting body. a) is attached to the supporting body in the CFRP state by spraying, scraping, pouring, spreading or rolling of the slurry, and the firmly-adhering, flat layer resulting after the drying at 20°C to 60°C is cured by heating to a temperature from 120°C to 280°C, or b) as a preform produced from the slurry, wherein a film is poured from the slurry from which friction disks are stamped after drying to a leather-like flat structure, and these are cured into a friction disk in the CFRP state by heating to a temperature from 120°C to 280°C, or c) as a preform in friction disk-form produced from the slurry according to the slurry casting method, wherein a mould made from a porous, water-absorbing material is provided into which the slurry is filled, and wherein after the delivery of the dispersing agent in the mould, a dry preform is extracted from this, which is cured into a friction disk in the CFRP state at a temperature from 120°C to 280°C, or d) as a friction disk which is injection moulded from the slurry after pre-draining, thickening and plasticising, wherein - the slurry is firstly pre-drained and thereby thickened, then - the pre-drained, thickened slurry is plasticised by heating and - injection-moulded into a friction disk, which is cured into a friction disk in the CFRP state in a separate step by heating to a temperature from 120°C to 280°C, - the slurry is firstly pre-drained and thereby thickened, then - the pre-drained, thickened slurry is plasticised by heating and - injection-moulded into a friction disk,
