Abstract
Official abstract text for this publication.
Composite reinforcer (R- 2 ) self-adhesive, by curing, 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, a polyamide 6,6, covering individually said thread or each thread or collectively several threads; a second layer ( 22 ) comprising a functionalized diene elastomer bearing functional groups selected from epoxide, carboxyl, acid anhydride and acid ester groups, for example, an epoxidized natural rubber, covering the first layer ( 21 ). Process for manufacturing such a composite reinforcer and rubber article or semi-finished product, especially a tire, incorporating such a composite reinforcer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composite reinforcer comprising: one or more reinforcing thread(s); a first layer of a thermoplastic polymer, the glass transition temperature of which is positive, covering said thread, individually each thread or collectively several threads; and a second layer consisting of a functionalized diene elastomer bearing functional groups selected from epoxide, carboxyl, acid anhydride and acid ester groups, covering the first layer.…
