Abstract: A clutch assembly for a motor vehicle drivetrain includes a rigid support and a wet friction material fixed to a surface of the rigid support. The wet friction material includes a base material including a matrix of fibers and filler particles embedded in the matrix of fibers; and a binder embedded in the base material. The base material includes, by weight percent, 30-55% cellulose fibers and 10-50% calcined kaolin clay. The base material also includes at least one of 1-20% graphite having a mean particle size of 35 to 85 microns, 20-40% diatomaceous earth in combination with the binder being tung modified phenolic resin, 5-20% chopped aramid fibers, or 5-20% of novoloid fibers.

Abstract: A clutch plate includes first and second axially offset annular surfaces, a first angled surface extending at an acute angle from the first annular surface in a first axial direction, and a second angled surface extending at an acute angle from the first annular surface in a second axial direction, opposite the first axial direction. In some example embodiments, the clutch plate has a wet friction material fixed to the first and second annular surfaces and at least one of the first and second angled surfaces. In an example aspect, the clutch plate has a low friction wet friction material fixed to the wet friction material of the at least one of the first and second angled surfaces. The low friction wet friction material may be fixed to the wet friction material by infusion or bonding. In an example embodiment, the clutch plate has a first wet friction material fixed to the first and second annular surfaces, and a second, low friction wet friction material fixed to at least one of the first and second angled surfaces.
