Abstract
A composite comprises at least one reinforcing element exhibiting a surface comprising an alloy of copper and zinc, the reinforcing element being embedded in an elastomeric composition based on at least a diene elastomer, a reinforcing filler, a sulfur crosslinking system and a phenol/aldehyde resin based on at least one aromatic polyphenol and on at least one dialdehyde compound comprising two aldehyde functions, in which the content of phenol/aldehyde resin is less than 10 phr.
Claims15
A composite comprising at least one reinforcing element exhibiting a surface comprising an alloy of copper and zinc, the reinforcing element being embedded in an elastomeric composition based on at least a diene elastomer, a reinforcing filler, a sulfur crosslinking system and a phenol/aldehyde resin based on:
- at least one aromatic polyphenol comprising at least one aromatic nucleus bearing at least two hydroxyl functions in a meta position with respect to each other, the two positions ortho to at least one of the hydroxyl functions being unsubstituted, and
- at least one dialdehyde compound comprising two aldehyde functions, in which a content of phenol/aldehyde resin is less than 10 phr.
