Abstract
A friction material is provided for a friction member of a torque-transmitting mechanism. The friction member has a woven carbon fiber fabric base. A coating is applied to the base to form a portion of a contact surface positioned to contact a reaction member during engagement of the torque-transmitting mechanism. The coating is a mixture of a resin binder and a friction modifier. A method of forming a friction material is also provided.
