PRESSURE-SENSITIVE COMPOSITE REINFORCEMENT

摘要

The invention relates to a composite reinforcement (R-2) suitable for directly adhering to a diene rubber die, which can be used as a reinforcing element for a tire, comprising: one or more reinforcement wire(s) (20), for example a carbon steel cable; a first layer (21) of a thermoplastic polymer having a positive glass-transition temperature, for example a 6-6 polyamide, covering said wire(s); a second layer (22), comprising a thermoplastic unsaturated styrene elastomer ("TPS") having a negative glass-transition temperature, for example an SB (styrene-butadiene) or SBS (styrene-butadiene-styrene) block copolymer, as well as a poly(p-phenylene ether) ("PPE"), covering the first layer (21). The invention also relates to a method for manufacturing such a composite reinforcement and to a semi-finished rubber article or product, in particular a tire, including such a composite reinforcement.
