摘要： A radial tyre, which is useable for a passenger vehicle or a van, has a crown reinforcement or belt having a lightened belt structure. The lightened belt structure is constructed of a multilayer composite laminate that includes a first layer of rubber that radially surmounts, in a direction Z, two other layers of rubber. The first layer of rubber includes weakly heat-shrinkable textile circumferential reinforcers, for example, made of nylon or polyester. The two other layers of rubber are reinforced with monofilaments of high tensile steel. The multilayer composite laminate allows the tyre's weight and rolling resistance to be reduced without impairing the tyre's cornering stiffness and, therefore, road holding and handling. At the same time, the multilayer composite laminate enables the tyre to have a running endurance that is at least equivalent if not better than that of a conventional tyre.
摘要翻译： 可用于客车或厢式货车的子午线轮胎具有带有减轻带结构的胎冠加强件或带。 减轻的带结构由多层复合层压板构成，其包括第一层橡胶，其沿Z方向径向超过另外两层橡胶。 第一层橡胶包括弱热收缩织物周向加强件，例如由尼龙或聚酯制成。 另外两层橡胶用高强度钢的单丝增强。 多层复合层叠体能够降低轮胎的重量和滚动阻力，而不会损害轮胎的转弯刚度，并因此降低道路的保持和搬运。 同时，多层复合层压板使轮胎的运行耐久性至少等同于传统轮胎的耐久性。

A tread width TW and a cross-sectional width Wca of the carcass layer have a relationship such that 0.82≦TW/Wca≦0.92. A width Ws of the circumferential reinforcing layer and a cross-sectional width Wca of the carcass layer such that 0.60≦Ws/Wca≦0.70.

摘要： A flat or planar reinforcer shaped as a multicomposite strip (R1), which is defined by three main perpendicular directions: an axial direction (X), a transverse direction (Y), and a radial direction (Z), has a width LR in the Y direction of between 2 and 100 mm, and has a thickness ER in the Z direction of between 0.1 and 5 mm. A ratio LR/ER is greater than 3. The multicomposite strip includes a plurality of monofilaments made of a composite material. The monofilaments are oriented along the X direction and include filaments of a mineral material embedded in a thermoset resin having a glass transition temperature Tg1 that is greater than 70° C. The monofilaments are coated in a layer of thermoplastic material. The reinforcer may be used to reinforce a tire and a multilayer laminate, which may be used to reinforce a tire.
