Abstract: A multi-layered carbon ceramic brake disk has at least one carrier body, and at least one ventilation layer that containing ventilation ducts, and optionally, at least one friction layer. The brake disk is made by joining green bodies of at least one individual carrier body, green bodies of at least one individual ventilation layer, and optionally, green bodies of at least one individual friction layer. The green bodies contain thermoplastic or thermoset polymeric materials, in their solid or cured states, and by subsequent carbonization and ceramicization by infiltration with carbide-forming elements.

Abstract: Composite brake disk comprising a brake disk ring and a brake disk chamber having at least three fastening means for connection of the brake disk ring and brake disk chamber, the fastening means being blind rivets with a holding force in both directions parallel to the rivet axis, selected from cup rivets, tension pin rivets, pull-through rivets and removable pull-through rivets.

Abstract: A method of processing water-sensitive ceramic powders, particularly carbothermically produced aluminum nitride, whereby the ceramic powder is deagglomerated in a dry milling step with addition of an alkylamine which is liquid at room temperature is disclosed. The alkylamine is added in an amount sufficient to produce a monomolecular layer on the surface of the ceramic powder. The deagglomerated powder subsequently is vigorously stirred with a concentrated aqueous solution or dispersion of binder and rapidly and gently dried, preferably by freeze drying. Aluminum nitride powder prepared by this process can be further processed into shaped parts with a high thermal conductivity.
