Method for producing cylindrical annular friction discs having a defined relief crack microstructure in the friction layer, comprising the steps of - producing a preform for the support body made of porous carbon, which preform is preferably reinforced with high-temperature-resistant fibres, - producing a preform for the friction layer body made of porous carbon, which preform preferably contains silicon carbide as a filler, - adhesively bonding at least one friction layer preform to the preform for the support layer by means of an adhesive layer containing, as an organic binder, a curable synthetic resin and optionally pitch and/or a thermoplastic, and at least one additive selected from the group consisting of elemental carbon, carbides, nitrides and silicides of metals and semi-metals of groups 3b, 4b and 5b of the periodic table of the elements, high-temperature-resistant fibres selected from carbon fibres, fibres of binary and ternary compounds of the elements Si, C, N, B, O and P, and whiskers of refractory metals, - pyrolysing the formed composite with the elimination of oxidising agents, with the formation of carbon from the organic binder, - infiltrating the carbonised composite with liquid silicon or a liquid alloy containing a mass fraction of at least 50 % silicon, with the formation of carbides of silicon and optionally of the other alloy components, and - cooling the siliconised composite according to a selectable temperature profile, in which an intermediate layer is formed from the adhesive layer by the steps of carbonisation and infiltration with subsequent reaction to form carbides, characterised in that the adhesive layer is formed - from a carbon filament bundle mesh which has a plain weave and is impregnated or coated with an adhesive which can be converted into carbon by heating with the elimination of oxidising substances to temperatures of 800 °C or more, - by uneven application of an adhesive preferably in the form of a grid which more preferably intersects at right angles, or a spider's web having concentric circles or spirals and radii that intersect these circles or spirals, by screen printing or by means of a computer-controlled applicator, or - by solidifying the adhesive on an anti-adhesively treated smooth surface to form a film, from which a grid-shaped overlay is punched out, which returns to an adhesive state after further heating before reaching the state of a cross-linked and non-melting thermoset. - producing a preform for the support body made of porous carbon, which preform is preferably reinforced with high-temperature-resistant fibres, - producing a preform for the friction layer body made of porous carbon, which preform preferably contains silicon carbide as a filler, - adhesively bonding at least one friction layer preform to the preform for the support layer by means of an adhesive layer containing, as an organic binder, a curable synthetic resin and optionally pitch and/or a thermoplastic, and at least one additive selected from the group consisting of elemental carbon, carbides, nitrides and silicides of metals and semi-metals of groups 3b, 4b and 5b of the periodic table of the elements, high-temperature-resistant fibres selected from carbon fibres, fibres of binary and ternary compounds of the elements Si, C, N, B, O and P, and whiskers of refractory metals, - pyrolysing the formed composite with the elimination of oxidising agents, with the formation of carbon from the organic binder, - infiltrating the carbonised composite with liquid silicon or a liquid alloy containing a mass fraction of at least 50 % silicon, with the formation of carbides of silicon and optionally of the other alloy components, and - cooling the siliconised composite according to a selectable temperature profile, in which an intermediate layer is formed from the adhesive layer by the steps of carbonisation and infiltration with subsequent reaction to form carbides, - from a carbon filament bundle mesh which has a plain weave and is impregnated or coated with an adhesive which can be converted into carbon by heating with the elimination of oxidising substances to temperatures of 800 °C or more, - by uneven application of an adhesive preferably in the form of a grid which more preferably intersects at right angles, or a spider's web having concentric circles or spirals and radii that intersect these circles or spirals, by screen printing or by means of a computer-controlled applicator, or - by solidifying the adhesive on an anti-adhesively treated smooth surface to form a film, from which a grid-shaped overlay is punched out, which returns to an adhesive state after further heating before reaching the state of a cross-linked and non-melting thermoset.
