  • Patent number: 7405010
    Abstract: A metallic body of carbon steel covered with an adhesive layer capable of adhering to a rubber matrix based on diene elastomer. The carbon content of the steel is between 0.35 and 1.2% by weight. The adhesive layer is formed of a metallic layer bearing aluminum oxides or hydroxides, which itself is covered with an organosilane film which is at least bifunctional, capable of ensuring, as coupling agent, the bond between the aluminum oxides or hydroxides on one hand, and the rubber matrix on the other hand.
    Type: Grant
    Filed: March 1, 2006
    Date of Patent: July 29, 2008
    Assignee: Michelin Recherche et Technique S.A.

  • Patent number: 7066228
    Abstract: A (metal/rubber) composite comprising a rubber matrix reinforced with a metallic body adhering to the rubber matrix by means of an adhesive interphase; the rubber matrix is based on diene elastomer; the metal is a carbon steel, the carbon content of which is between 0.35% and 1.2%; to constitute the adhesive interphase, the carbon steel is coated with a metallic layer bearing aluminium oxides or hydroxides, which itself is covered by an organosilane film providing, as coupling agent, the bond between the aluminium oxides-hydroxides on one hand, and the rubber matrix on the other hand. The invention also relates to articles or semi-finished products made of rubber which are reinforced with or formed by such a composite, in particular tires.
