<p>A composite friction unit of a three dimensional composite body is formed of a substantially uniform array of predominately glass strands of primary reinforcing fibers in matrix of phenolic resin material, the reinforcing fiber in the form of fabric distributed throughout the body forming a friction unit having a predetermined size and configuration and uniform distribution and alignment of fibers throughout. An alternate friction unit includes a laminate with a substantially rigid backing co-pultruded through a forming die in forming the unit. The units are produced in a pultrusion process wherein the reinforcing fibers and matrix are pulled through a forming die.</p> |
