Abstract
A composite friction unit includes a three dimensional composite body formed of a substantially uniform array of predominately glass strands of primary reinforcing fibers in matrix of phenolic resin material, the reinforcing fibers distributed throughout the body in a predetermined uniform distribution and orientation, and a substantially uniform array and distribution of secondary fibers extending transverse to the primary fibers thereby forming a friction unit having a predetermined size and configuration and uniform distribution and alignment of fibers throughout.
Claims6
A continuous manufacturing process for making composite friction units comprising the steps of:
- selecting a substantially uniform array of predominately glass strands of primary reinforcing fibers;
- wetting said plurality of strands of primary reinforcing fibers with a phenolic resin material;
- pulling said wetted strands of reinforcing fibers in a predetermined uniform distribution and orientation through a composite forming die for forming a body having a peripheral configuration of said friction units;
- introducing a continuous array of predominately transverse secondary fibers between selected pairs of said plurality of primary fibers prior to entry into said forming die;
- solidifying said body by curing said resin;
- and
- selectively cutting said body at least along one path transverse to said strands into it plurality of said friction units, thereby forming a plurality of friction units having a predetermined size and configuration and uniform distribution and alignment of fibers throughout.
