摘要： Disclosed is a brake disk. The brake disk includes a friction part having a coupling aperture within a center thereof and a plurality of recessed portions repeatedly formed at a predetermined interval along an inner circumference of the coupling aperture, in which bevels protrude from inner surfaces of the recessed portions, respectively. The bevels are tapered along upper and lower sides thereof toward protruding centers. The brake disk also includes a hub having a plurality of protrusions inserted into and attached to the recessed portions when coupled to and received in the coupling aperture of the friction part via a cast-bonding method, along a circumference thereof.

摘要： This invention relates to a paper friction material and a method of manufacturing the same, wherein the paper friction material is configured such that dispersibility and bondability are increased between a filler and a matrix. The paper friction material which is suitable for use in a vehicle, includes a friction base including pulp and a coating layer formed on the friction base using a mixture of latex and a functional material. The OH reactive group of the pulp and the aromatic ring of the latex are hydrogen-bonded so that the friction base and the coating layer are coupled with each other.
