Glass-resin multicomposite reinforcement with improved properties

Abstract

A multicomposite reinforcer (R1, R2) comprises one or more monofilament(s) (10) made of glass-resin composite comprising glass filaments (101) embedded in a crosslinked resin (102), with a glass transition temperature Tg1. A layer of a thermoplastic material (12), the glass transition temperature of which, denoted Tg2, is greater than 20° C., covers said monofilament or, if there are several, individually covers each monofilament or collectively covers all or at least some of the monofilaments. Said monofilament or, if there are several, all or at least some of the monofilaments has the following features: a temperature Tg1 equal to or greater than 190° C.; an elongation at break A(M) equal to or greater than 4.0%; and an initial tensile modulus E(M) greater than 35 GPa. A multilayer laminate may comprise such a multicomposite reinforcer. A pneumatic or non-pneumatic tyre may be reinforced with such a multicomposite reinforcer or multilayer laminate.
