  • Process for producing carbon-ceramic brake discs
    Patent number: 7993549
    Abstract: Process for producing carbon-ceramic brake discs comprising the following steps: production of a carbonized core body by press-molding a mixture containing reinforcing fibers and a binder, curing the binder by heating, and carbonizing by heating the press-molded body under exclusion of oxidizing substances to a temperature of between 750° C. and 1300° C., press-molding a moldable, reinforcing fiber-containing material onto the prefabricated carbonized core body which after the additional process steps produces the friction layer, curing the material for the friction layer, carbonizing the entire body and then infiltrating the composite body with liquid silicon.

  • Process for producing hollow comprising fiber-reinforced ceramic materials
    Patent number: 7276203
    Abstract: A process for producing hollow bodies comprising fiber-reinforced ceramic materials, in which a green body comprising compressible cores and a mouldable composition comprising binders and fiber material which is pressed with compression of the core is produced, the green body is cured and carbonized and pyrolysed by heating in a nonoxidizing atmosphere and, if desired, the body is silicized, hollow bodies produced in this way and their use, in particular as brake and clutch disks
