Abstract
Abstract A heavy duty rubber composite having a reinforcement structure is described, wherein the reinforcement structure is 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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
77 words
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.
Claim 2
Dependent Claim
77 words
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.
Claim 3
Dependent Claim
28 words
The composite as claimed in claim 1, wherein the open-mesh structure of the network material is a textile material made from a knitted fabric or from extensible filaments.
Claim 4
Dependent Claim
21 words
The composite as claimed in claim 1, wherein the network material contains a structure-stabilizing resin in addition to the rubber material.
Claim 5
Dependent Claim
20 words
The composite as claimed in claim 1 wherein the composite contains, besides the network material, other fibrous materials as reinforcements.
