THREE-DIMENSIONAL FLEXIBLE LAMINATE WITH HIGH PITCH RESISTANCE AND PERFORATIONS, GLOVE AND PNEUMATIC ENVELOPE CONSISTING OF SAID STRATIFY

摘要

The present invention relates to a flexible three-dimensional laminate of high puncture and perforation resistance, such as a glove (1) or a tire envelope, which comprises at least one metallic inner layer forming a barrier to these punctures and perforations.A laminate according to the invention. The invention comprises at least one inner metal layer forming a barrier to punctures and perforations, the or each layer having a thickness of less than 50 μm and comprising at least one metal sheet (2) of continuous structure having a width greater than 10 mm and or a length greater than 50 mm, which has both the following properties, measured at 20 degrees C: (i) a yield strength Rp0.2 (at 0.2% relative elongation) greater than 1200 MPa (ii) a Young's modulus less than 210 GPa, and (iii) a tensile strength greater than 1200 MPa.
