Abstract

The invention relates to a reinforcing element (50) comprising a plurality of strands (T) arranged in a single-layer arrangement with each strand (T) consisting of: - a core consisting of a textile filament element (36); and - a layer comprising at least two metal filament elements (38) helically wound around the core; wherein the diameter Df of each metal filament element (38) ranges from 0.04 to 0.10 mm.

Abstract

The invention relates to a cable comprising at least one strand (T) having at least two layers (C1, C3), comprising: - an inner layer (C1) consisting of Q inner metal wire(s) (F1) of diameter Df1, and - an outer layer (C3) consisting of N outer metal wires (F3) of diameter Df3 wound around the inner layer (C1), wherein the diameter Df1, Df3 of each metal wire (F1; F3) ranges from 0.04 to 0.10 mm and wherein each metal wire (F1; F3) has a breaking strength, denoted Rm, greater than or equal to 3700 MPa determined by ISO standard 6892-1 of October 2009. The diameter of the cable (50) ranges from 0.12 to 0.60 mm.

Abstract

The invention relates to a rubber composition having a good performance compromise between elongation at break, tear strength and fatigue resistance. This composition is based on at least one elastomer matrix comprising from 85 to 98 phr of at least one copolymer containing ethylene units and 1,3-diene units, the molar fraction of ethylene units in the copolymer being within a range extending from more than 50% to 95%, and from 2 to 15 phr of a polyisoprene comprising a content by weight of cis-1,4 bonds of at least 90% of the weight of the polyisoprene, a reinforcing filler comprising carbon black having a BET specific surface area within a range extending from 50 to 160 m2/g, and a crosslinking system. The invention also relates to a tyre comprising this composition.
