Abstract

L’invention concerne un produit renforcé (R1) comprenant une matrice polymérique (Ma) et au moins un câble (50) comprenant une unique couche constituée de N éléments de renforcements métalliques étant :- ou bien des fils métalliques (F) présentant un diamètre Df, avec les éléments de renforcement métalliques (54) présentant un diamètre Dh qui est le diamètre du cercle théorique passant par les centres des fils (F) de la couche dans un plan perpendiculaire à l’axe principal du câble et un diamètre D qui est le diamètre extérieur du câble (50); - ou bien des torons (T) enroulés en hélice autour d’un axe principal (A), chaque toron (T) comprenant une unique couche (56) constituée de M>1 de fils métalliques (FT) enroulés en hélice autour d’un axe (B) présentant un diamètre Df avec les éléments de renforcement métalliques (54) présentant un diamètre Dh qui est le diamètre du cercle théorique passant par les centres des fils (FT) de la couche (56) dans un plan perpendiculaire à l’axe principal du toron (T) et un diamètre D qui est le diamètre extérieur du toron (T) ;avec D, Dh et Df exprimés en millimètres :- 0,20 < Jr ≤ 0,30Avec Jr=N/(π x (D-Df)) x (Dh x Sin(π/N) – (Df / Cos(α x π/180))), α étant l’angle d’hélice, exprimé en degrés, de chaque fil métallique  ;- la matrice polymérique (Ma) présente un module élastique sécant MA10 à 10% de déformation allant de 2,5 à 18,0 MPa ;- le produit renforcé (R1) présente un rapport de module Emax sur Emin tel que 1< Emax/Emin <5  avec Emin étant le module élastique minimum sécant à partir de la courbe force-allongement avant le point d’allongement structural As et Emax étant le module maximum tangent de la même courbe force-allongement; et- le produit renforcé (R) présente un allongement structural As tel que 0< As < 3%.
