Abstract: A disk assembly having a circular friction lining mounted on one or both sides of a support member. An oil channel extends from the outer edge of the friction lining to the inner edge. The oil channel includes an enlarged middle oil reservoir section extending completely through the friction lining. An inlet section and an outlet section of the oil channel are in communication with the reservoir section and are narrow grooves which are embossed in the friction lining during bonding of the friction lining.

Abstract: A method for making a core plate (42) having multiple friction material segments (54) on the surface where the method includes the use of a die (24). Friction material (34) is first trimmed to conform to die (24) and is then fed into die (24). Die (24) then cuts friction material (34) to form a leading edge (57) where fibers in friction material (34) at leading edge (57) are positioned in a direction toward core plate (42). Friction material (34) is then fed through die (24) which cuts a trailing edge (55) in friction material (34) where fibers in friction material (34) at trailing edge (55) are positioned in a direction toward core plate (42). Cutting of trailing edge (55) is a common cut along trailing edge (55) of a leading segment (54) and leading edge (57) of an immediately following segment (54) such that formation of segments (54) is substantially scrapless with respect to friction material (34).

Abstract: The present invention relates to a fibrous base material comprising a primary layer of less fibrillated aramid fibers, synthetic graphite and at least one filler material, and a secondary layer of carbon particles on at least one surface of the fibrous base material for use in a non-asbestos friction material. In certain embodiments, the fibrous base material is impregnated with a phenolic or phenolic-based resin material, including, for example, a mixture of a phenolic resin and a silicone resin to form a friction material having good "break-in" and durability characteristics.
