Abstract

A multilayer laminate, which is usable as a reinforcing element for a finished article or for a semifinished product made of rubber, such as a tire, includes at least one polymer film having, in any tensile direction in the film's plane, a Young's modulus that is greater than 500 MPa. The film is positioned between and in contact with two layers formed of a rubber composition, such as natural rubber. Each layer formed of the rubber composition exhibits, in a crosslinked state, a secant modulus that, in extension at 10% elongation, is greater than 30 MPa, with between 30 and 150 MPa being preferable for the secant modulus.
