Abstract

A heavy duty rubber composite has a reinforcement structure composed of a network material made from a three-dimensionally shaped textile material forming an open-mesh three-dimensional network which penetrates the rubber material three-dimensionally in a skeleton-like manner. The network material is advantageously firmly incorporated into the rubber composite by appropriately linking the network material with the other reinforcements present in the rubber composite.

Claims

1. A vehicle tire including a heavy duty rubber composite comprising a reinforcement structure composed of a network material made from a textile material of natural or synthetic fibers forming a filigree-like open-mesh network containing rods, knots and cavities, the open mesh network being shaped in three dimensions to include a plurality of cup-shaped deformations arranged in a regular pattern and extending in a direction generally perpendicular to a planar portion of the network material, and rubber material surrounding the reinforcement structure.

2. The vehicle tire as claimed in claim 1, wherein the network material forms a seamless reinforcement structure.

3. The vehicle tire as claimed in claim 1, wherein the tire includes a carcass structure and a belt structure each having reinforcement fibers, and the network material is located on top of the reinforcement fibers of the carcass structure and of the belt structure and is anchored by means of anchoring elements in the carcass structure and belt structure.

4. The vehicle tire as claimed in claim 1, wherein the tire includes a tread, a carcass structure, and a belt structure, the carcass structure and belt structure each having reinforcement fibers, a proportion of the reinforcement fibers of the carcass and/or of the belt structure being incorporated into the network material, the proportion of incorporated reinforcement fibers penetrating the network material in the planar portion thereof and extending in a direction perpendicular to the plane of the tread.

5. The vehicle tire as claimed in claim 1, wherein the tire includes a carcass structure and a belt structure each having reinforcement fibers and the planar portion of the network material is encircled or penetrated by the reinforcement fibers of the carcass structure and/or of the belt structure.
