<p>The dry friction plate is basically annular and flat in shape, is made from a friction material (16) bounded by inner (12) and outer (14) cylindrical surfaces, and has at least one annular reinforcing zone (18) or a series of concentric reinforcing zones. The reinforcing zones are situated adjacent to the plate's inner cylindrical surface and can be made from materials with the same density or different densities decreasing from the inner cylindrical surface outwards. Each reinforcing zone is in the form of a ring insert made from an organic, mineral and/or metallic material, e.g. a wire, fibres, a fabric, braid or strip, while the plate itself comprises a fibre mat made from fibres between 40 and 120 mm long, impregnated with a thermo-setting resin.</p> |
