摘要： A brake disc, in which a hat part that is mounted on a hub and a disc part that provides friction surfaces with brake pads are made of different materials and are combined, includes: a plurality of bridges protruding and circumferentially arranged around an edge of the hat part for coupling to the disc part; a plurality of vanes defining a channel for air flow; and a plurality of coupling pillars, which are fixedly in contact with the bridges, respectively, arranged between a pair of disc plates. The coupling pillars are fixedly in contact with both sides of the bridges while exposing front ends of the bridges.

摘要： Disclosed are a brake disk and a method for manufacturing the same. In particular, the brake disk may include a friction surface formed of cast iron, and the friction surface of the brake disk is divided into a plurality of sections in a circumferential direction. Preferably, an average of the numbers per unit area of eutectic cells formed on surfaces of the sections may not be greater than 300 ea/cm2.

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.
