Sliding unit for a brake and method of producing the same

摘要

A sliding unit for a brake comprising a disk and pads made of carbon-fiber reinforced carbon composite materials, characterized in that in evaluation by X-ray diffraction, the sliding surface of the disk to the pads has interplanar spacing of graphite's reflection (002) of disk d002(disk) of 3.37 ANGSTROM - 3.43 ANGSTROM , and intensity ratio I(disk)/Ic of 60 - 90, which is obtained by dividing the integrated intensity of graphite's reflection (002) of disk I(disk) by the integrated intensity of (113) of alpha -A l 2O3 as a reference material Ic; the sliding surface of the pads to the disk has interplanar spacing of graphite's reflection (002) of pad d002(pad) of 3.42 ANGSTROM - 3.44 ANGSTROM , and intensity ratio I(pad)/Ic of 45-75, which is obtained by dividing the integrated intensity of graphite's reflection (002) of pad I(pad) by the integrated intensity of (113) of alpha -A l 2O3 as a reference materials Ic, and d002(disk)
