Abstract
Official abstract text for this publication.
Composite reinforcement (R- 2 ) that is self-adhesive by curing to a diene rubber matrix, which can be used as reinforcing element for a tire, comprising: at least one reinforcing thread ( 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; and a second layer ( 22 ) comprising an unsaturated thermoplastic stirene elastomer, the glass transition temperature of which is negative, for example an SBS (stirene-butadiene-stirene) copolymer, 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composite reinforcement comprising: at least one reinforcing thread; a first layer of a thermoplastic polymer, the glass transition temperature of which is positive, covering said thread; and a second layer comprising an unsaturated thermoplastic styrene elastomer, the glass transition temperature of which is negative, covering the first layer; wherein the unsaturated thermoplastic styrene elastomer of the second layer is crosslinked.…
