METHOD FOR MANUFACTURING A CARBON-CERAMIC BRAKE DISK

A method of manufacturing a carbon-ceramic brake disc of the present invention includes a first step of coating PAN-based carbon fibers with phenolic resins; a second step of carbonizing the PAN-based carbon fibers, which have been coated with the phenolic resins, at a first temperature; a third step of mixing the PAN-based carbon fibers, which have been carbonized at the first temperature, with the phenolic resins to produce a mixture; a fourth step of putting the mixture into a mold to produce a molded body through pressing by means of a press; a fifth step of carbonizing the molded body at a second temperature equal to or less than the first temperature; a sixth step of machining the carbonized molded body; a seventh step of melting silicon to be infiltrated into the machined molded body; and an eighth step of grinding the molded body that has been infiltrated by the silicon. According to the present invention, even after the silicon is melted to be infiltrated into the molded body, the PAN-based carbon fibers are maintained in their original shapes without being changed, so that the PAN-based carbon fibers are not easily broken when a brake is operated. Accordingly, it is possible to consistently maintain strength of the carbon-ceramic brake disc.
