|20140054810||METHOD FOR REFURBISHING AN AIRCRAFT BRAKE DISK - Provided is a method for refurbishing an aircraft brake disk, the method comprising: removing a worn disk from the aircraft brake disk when the disk is worn out up to a set wear amount (Step 1); filling a first mixture in a mold to be a first refurbishment height (Step 2); putting the worn disk on the first mixture (Step 3); filling a second mixture on the worn disk in the mold to be a second refurbishment height (Step 4); pressurizing the first mixture, the worn disk, and the second mixture with a press at once to prepare a molded object (Step 5); removing the molded object from the mold, and then carbonizing the molded object (Step 6); and densifying the carbonized molded object (Step 7), in which the worn disk is subjected to Steps 1 to 7 to prepare a refurbished disk.||02-27-2014|
|20130248305||CARBON-CERAMIC BRAKE DISK AND METHOD FOR MANUFACTURING SAME - A method of manufacturing a carbon-ceramic brake disc of the present invention includes a first step of mixing carbon fibers with phenolic resins to produce a mixture; a second step of putting the mixture into a mold pressing the mixture by a press to produce a molded body; a third step of carbonizing the molded body; a fourth step of machining the carbonized molded body; a fifth step of coating the machined molded body with liquid-phase phenol to be cured; a sixth step of melting silicon to be infiltrated into the cured molded body that has been coated with the liquid-phase phenol; and a seventh step of grinding the molded body that has been infiltrated by the silicon. According to present invention, the cracks do not occur in the anti-oxidation coating layer.||09-26-2013|
|20130248304||CARBON-CERAMIC BRAKE DISK - The present invention relates to a carbon-ceramic brake disc, and the present invention includes a plurality of heat dissipation holes formed in a frictional surface; a curved surface formed between the frictional surface and an inner surface of the hole dissipation hole; and a groove formed at the inner surface of the heat dissipation hole. According to the present invention, in a brake system, when brake pads press the frictional surfaces of the carbon-ceramic brake disc brake to generate braking force, frictional heat in the carbon-ceramic brake disc is effectively dissipated to the outside. That is, the carbon-ceramic brake disc is effectively cooled. Thus, the transferring of the frictional heat generated in the carbon-ceramic brake disc to a hat part is reduced, so that it is possible to minimize deformation of the carbon-ceramic brake disc and the hat part.||09-26-2013|
