BRAKE DISC COMPRISING HETEROGENEOUS MATERIALS AND METHOD FOR MANUFACTURING THE SAME

摘要

Disclosed is a brake disc manufactured from heterogeneous materials and a method for manufacturing the brake disc. The brake disc includes a friction part in which a connection hole is formed in a center, protrusions and recesses are alternately repeated along a circumference of the connection hole, the recess has a shape curved in an opposite direction of the connection hole. The brake disc also includes a hat part that is made of material different from that of the friction part, and has insertion grooves formed along an outer circumference so as to allow the protrusions to be inserted. Particularly, heat radiation holes are formed along the circumference of the connection hole at predetermined distance by connecting insertion parts of the protrusions to the insertion grooves of the hat part with a predetermined gap from an inner surface of the friction part. Also provided is a brake disc manufactured from heterogeneous materials having excellent durability.
