Title (EN) TYRE COMPRISING A PROTECTIVE LAYER HAVING IMPROVED ENDURANCE PROPERTIES
(FR) PNEUMATIQUE PRESENTANT UNE COUCHE DE PROTECTION AVEC DES PROPRIETES D'ENDURANCE AMELIOREES
Abstract: front page image
(EN)The invention relates to a tyre comprising a crown reinforcement formed by at least two working crown layers of reinforcing elements and at least one protective layer. According to the invention, the tensile modulus of elasticity at 10% elongation of at least the radially outermost skim coat of at least one protective layer is less than 8.5 MPa, and at least said skim coat has a electrical volume resistivity ρ such that log(ρ) is greater than 8.
(FR)L'invention concerne un pneumatique comprenant une armature de sommet formée d'au moins deux couches de sommet de travail d'éléments de renforcement et d'au moins une couche de protection. Conformément à l'invention,le module d'élasticité sous tension à 10% d'allongement d'au moins la couche de calandrage radialement la plus extérieure d'au moins une couche de protection est inférieur à 8,5 MPa, et au moins ladite couche de calandrage présente une résistivité électrique volumique ρ telle que log(ρ) est supérieur à 8.
