The invention relates to a compressible, shear-force absorbing and sealing laminate structure comprising two rubber layers and an intermediate metal layer. According to the invention, the laminate structure comprises two thin carrier-calendared rubber films, each having a thickness of at least about 0.05 mm, and a thin metal plate disposed between the rubber films, wherein each rubber film is affixed to the plate by vulcanization. The laminate finds use as gasket material, for instance in the manufacture of cylinder head gaskets for internal combustion engines.
L'invention concerne une structure de stratifié d'étanchement compressible, absorbant les forces de cisaillement, comprenant deux couches de caoutchouc et une couche intermédiaire métallique. La structure de stratifié selon l'invention comprend deux minces pellicules de caoutchouc calandré à l'aide d'un véhicule, présentant chacune une épaisseur d'environ 0,05 mm entre lesquelles est placée une mince plaque de métal, chaque pellicule de caoutchouc étant fixée à la plaque par vulcanisation. Ledit stratifié est utile en tant que joint d'étanchéité, par exemple dans la fabrication de joints de culasse de cylindres pour moteurs à combustion interne.
