  • Patent number: 6022502
    Abstract: A composite friction assembly is disclosed which comprises at least one friction member and a support member. Each of the friction member and the support member have a composition comprising a thermosettable resin and a filler material. The friction member and the support member each have a planar surface, with the respective planar surfaces being joined at their interface, so as to define a boundary layer. The composition of each member is substantially confined to separate sides of the boundary layer whereby the composition of the friction member does not substantially penetrate beyond the boundary layer into the composition for the support member and the composition for the support member does not substantially penetrate beyond the boundary layer into the composition for the friction member. Among the disclosed embodiments of the present invention is a brake pad, such as that used in vehicular brakes. The present invention further relates to a method of making such a composite friction assembly.
