Abstract
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.
