ABSTRACT:
A milled blend is prepared, which comprises extremely short fibers and rubber as well as a suitable amount of long fibers having hair root-like branches or a number of whiskers and/or bent long fibers and, optionally, a suitable amount of fillers. The milled blend is then laminated under pressure on both sides of a hooked, corrugated or embossed thin metal sheet, and vulcanized in a suitable manner. The resulting sheet gasket excels in sealing properties, heat resistance and durability.
