Composite friction disk having replaceable wear faces

摘要

A friction brake includes a friction disk assembly having high dynamic stability against undesired vibration during a braking event. The friction disk assembly comprises an annular structural carrier of carbon and/or ceramic or other suitable structual material, preferably a fiber reinforced composite material, including a plurality of recessed regions and torque drive notches spaced around its circumferential direction, and a friction lining of carbon and/or ceramic or other suitable structural material, preferably a fiber reinforced composite material, mounted on the carrier, the friction lining having a flat wear (rubbing) face and an obverse face including raised areas corresponding to and matingly engaging the recessed regions of the carrier to prevent rotation of the lining relative to the carrier. The lining may be formed of of virgin or recycled carbon, ceramic or other suitable friction material. The lining may be retained to the carrier by mechanical fasteners such as rivets or clips. The assembly may be refurbished by simple replacement of the worn lining without need of machining. The carrier and the lining are preferably formed as unitary annular members.
