Abstract
A laminated composite body, in particular a conveyor belt, consists of a carcass (2, 2', 2") that determines the mechanical stability of the laminated composite body, and at least one cover (1, 1') made of rubber, thermoplastic elastomer (TPE) and/or plastics that are highly resistant to mechanical damages such as notches, cuts, or the like. In order to improve the resistance of the laminated composite body, the cover (1) is made of at least two layers (10, 11, 12) with different properties that are interconnected so as to form a clear phase limit.
Claims18
A laminated composite body comprising:
- a support for providing mechanical stability;
- and
- at least one cover plate having a multi-layer design which comprises a material which exhibits high resistance to mechanical damage and is selected from the group consisting of rubbers, thermoplastic elastomers, plastics, and mixtures thereof, wherein said cover plate comprises at least two layers which exhibit different properties and are joined to one another thereby forming a phase boundary between the layers for impeding the propagation of cracks and wherein the at least two layers comprise an outer first layer and a second layer, and wherein the outer first layer has a Shore A hardness of between 50 and 80 and the second layer has a Shore A hardness of between 35 and 60 wherein the hardness of the outer first layer is at least 10% higher than the hardness of the second layer, and the second layer has an elasticity of at least 55%, the elasticity of the second layer being at least 10% higher than the elasticity of the outer first layer.
