Abstract
Composite reinforcement (R-2) capable of adhering directly to a diene rubber matrix, which can be used as reinforcing element for a tire, comprising: one or more reinforcing thread(s) (20), for example a carbon steel cord; a first layer (21) of a thermoplastic polymer, the glass transition temperature of which is positive, for example 6,6 polyamide, covering said thread or said threads; a second layer (22) of a composition comprising an unsaturated thermoplastic stirene (“TPS”) elastomer, the glass transition temperature of which is negative, for example an SB (stirene/butadiene) or SBS (stirene/butadiene/stirene) block copolymer, as well as a poly(p-phenylene ether) (“PPE”), covering the first layer (21). Process for manufacturing such a composite reinforcement and rubber article or semi-finished product, especially a tire, incorporating such a composite reinforcement.
