Title:
FRICTION MATERIAL
Document Type and Number:
Japanese Patent JP2021109439
Kind Code:
A
Abstract:
To provide a friction material with improved performance properties in a wide variety of different wet clutch applications.SOLUTION: A friction-generating layer 12 presents a friction-generating surface 18 and includes a friction-generating material 30. The friction-generating material includes friction-adjusting particles 32. A core layer 14 is adjacent to the friction-generating layer and includes a core material 40. The core material includes core fibers 42. A third layer 16 is adjacent to the core layer such that the core layer is disposed between the friction-generating and third layers. The third layer presents a multi-functional surface 20 facing opposite the friction-generating surface of the friction-generating layer. The third layer includes a multi-functional material 50. The multi-functional material includes: multi-functional fibers; and/or woven fibers 52 chosen from aramid fibers, carbon fibers, cellulose fibers, acrylic fibers, polyvinyl alcohol fibers, glass fibers, mineral fibers, and combinations thereof. A resin is present in at least one of the friction-generating layer, the core layer and the third layer.SELECTED DRAWING: Figure 2
