Abstract:
In a method of fabricating a solidified, reinforced friction material shape, the steps of:placing and evenly distributing a first measured quantity of a friction material mixture comprised of friction particles, filler particles, and organic polymer binder particles in a mold cavity having a planform shape corresponding to the planform of said friction material shape;placing a non-metallic honeycomb core reinforcement in said mold cavity with complete penetration of only a lower portion of said non-metallic honeycomb core reinforcement through said evenly distributed first measured quantity of friction material mixture;placing and evenly distributing a second measured quantity of said friction material mixture in said mold cavity to more than completely fill the upper portion of said non-metallic honeycomb core reinforcement and a zone above; andcompressing said placed and evenly distributed friction material mixture measured quantities to an elevated isostatic pressure and elevating the temperature of said placed and evenly distributed friction material mixture measured quantities sufficiently to bond said friction material mixtures together and to said fiber-reinforced, non-metallic honeycomb core reinforcement by covalent bonds and electrostatic bonding to form said reinforced friction material shape.
