Title
(EN) GLASS-RESIN COMPOSITE-BASED MULTI-COMPOSITE MATERIAL
(FR) MATÉRIAU MULTI-COMPOSITE À BASE DE COMPOSITE VERRE-RÉSINE
Abstract
(EN)
The invention relates to a multi-composite material (R1, R2) comprising at least one monofilament (10) made of a glass-resin composite that comprises glass filaments (101) embedded into a thermoset polyester resin (102), said monofilament being covered with at least two stacked layers of different materials, a first layer (12) placed on the surface of the monofilament and a second layer (14) of polyester thermoplastic material sheathing the whole thing, characterised in that the first layer (12) is a benzoxazine and/or polybenzoxazine layer; the invention also relates to finished articles or semi-finished products made of rubber, such as vehicle tyres reinforced with such a material.
(FR)
Matériau multi-composite (R1, R2) comportant au moins un monobrin (10) en composite verre- résine comportant des filaments de verre (101) noyés dans une résine polyester thermodurcie (102), ce monobrin étant recouvert d'au moins deux couches superposées de matières différentes, une première couche (12) disposée en surface du monobrin et une deuxième couche (14) de matière thermoplastique polyester gainant le tout,caractérisé en ce que la première couche (12) est une couche de benzoxazine et/ou polybenzoxazine; articles finis ou produits semi-finis en caoutchouc, tels que des bandages pour véhicule, renforcés d'un tel matériau.
