ABSTRACT:
A method of forming a friction pad utilizing two distinct compounds. One of the compounds has a high fiber content and the other has a high flow characteristic. The compounds are placed in respective layers in a mold and are compressed to form a composite piece which is placed in a second mold cavity along with a perforated metal plate. Heat and pressure are then applied to the composite piece in the second mold cavity to cause the high flow characteristic compound to flow and enclose the metal plate such that the two compounds and the metal plate are firmly bonded into an integral friction pad.
