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.

Abstract: The present invention concerns hybrid layered cables some of which can be used to reinforce at least one crown protection ply of tyres for heavy vehicles or earthmovers, and others to reinforce the beads of tyres for light motorised vehicles such as motorcycles. The invention also concerns a composite fabric usable as a crown protection ply of such heavy vehicles or earthmovers, and a bead wire designed to reinforce the said beads and the aforesaid tyres. A hybrid layered cable (C) according to the invention comprises a non-metallic internal layer (Ci) and an unsaturated external layer (Ce) comprising strands (T) each of which is at least in part metallic and which are wound in helix around the said internal layer, the said cable having a relative elongation at break At, measured in tension in accordance with the standard ISO 6892 of 1984, which is higher than 7%.

Abstract: The present invention relates to a metal cable usable for reinforcing a carcass reinforcement for a tire, such as a heavy-vehicle tire, to a composite fabric usable as a ply for such a carcass reinforcement, to a carcass reinforcement comprising this fabric and to a tire incorporating this carcass reinforcement. A metal cable according to the invention comprises a textile wrap, and is such that said wrap is formed of an aromatic thermotropic polyester or polyester amide. A composite fabric according to the invention is such that it comprises a rubber composition which is reinforced by said cables. A tire according to the invention has its carcass reinforcement comprising said composite fabric.
