  • Publication number: 20070169867
    Abstract: Presented is a tire that includes a crown, which is extended by two sidewalls and two beads and which includes a carcass ply anchored in the beads. The crown includes at least one reinforcing crown ply that includes parallel cables, which are oriented relative to the circumferential direction by an angle ? of between 10 and 45 degrees. The crown further includes at least one hooping crown ply that includes cables oriented in the circumferential direction, which are wound in a spiral. The hooping crown ply is made of a composite fabric that includes a rubber composition based on at least one diene elastomer which is reinforced by hybrid cables that each have a ratio of final tensile tangent modulus:initial tensile tangent modulus which is greater than 10.

  • Patent number: 7222481
    Abstract: Hybrid cables, a process for obtaining such and a composite fabric usable in a tire incorporating the hybrid cables are disclosed. A tire and a mounted assembly which each incorporate such a composite fabric is also disclosed. The hybrid cable has a ratio of final tangent modulus:initial tangent modulus greater than 10. This hybrid cable consists of a textile core of an initial modulus of less than 900 cN/tex and a textile wrap of an initial modulus greater than 1300 cN/tex which is helically wound around the textile core.
