摘要： A friction material has a first layer of a base material and a second layer of at least one type of friction modifying particle having substantially symmetrical geometric shapes on a top surface of the base material. The second layer has an average thickness of about 30 to about 200 microns and the surface area coverage of about 80 to about 100% such that the top layer has a fluid permeability lower than the first layer.

摘要： A wet friction material for use in a wet clutch includes a friction interfacing surface for experiencing frictional engagement with an opposed surface in the presence of a lubricant. At least a portion of the friction interfacing surface comprises fibrillated nanofibers, which define a nanofibrous web, and friction adjusting particles held by the nanofibrous web. A cured resin may adhere the fibrillated nanofibers and the friction adjusting particles to provide structural support for the friction material.
