Abstract (en)

[origin: WO9964755A1] A friction disk assembly ready for bonding to a core plate, and a method of making the same. An adhesive (30) for bonding the friction disk assembly (34) to the core plate (32) is applied to the rear surface of the annular friction ring (20). The pre-applied adhesive eliminates the expense and hazard of handling volatile adhesives during bonding of the friction ring to the core plate. The annular friction ring can be formed from at least two adjoining arcuate segments of a friction material. A porous backing (28) and the adhesive layer are applied to the rear surface of the friction material (22). Alternatively, the annular friction ring is a unitary structure. In another embodiment, the adjoining arcuate segments of a friction material are retained in an annular ring by the adhesive, without the porous backing. A method of bonding the friction disk assembly to a core plate is also disclosed.
