<p>Friction material adapted for use, for example, as a brake lining is disclosed. The material is comprised of a rigid, thermosetting, heat-resistant organic resin, reinforcing fibers if desired, and in particulate form a crystalline mineral friction modifier of an isomorphous substittutional solid solution consisting essentially of atoms of metals and oxygen arranged as a mixed crystal in a normal spinel crystal lattice structure. There are at least two different metal atoms present in the crystal lattice, the total number of metal atoms having a total valence charge sufficient to maintain electrical neutrality. The friction material may be conventionally supported as by a shoe or disc.</p> |
