REINFORCED NON-WOVEN SHEET, ASSEMBLY COMPRISING SUCH SHEET, AND METHOD FOR PROCESSING A NON-WOVEN SHEET

Abstract

A nonwoven fabric (10) comprises at least one reinforcement zone (20a, 20b, 20c, 20d) to which fibers and / or filaments composing the fabric are bonded according to a reinforcement pattern (22) comprising a plurality of geometric shapes (24). The reinforcement zone extends over the entire length (l) of the fabric measured in a longitudinal direction (x1) and over a width (11, 12) strictly less than the width (1) of the fabric (10) measured in a lateral direction (y1) orthogonal to the longitudinal direction (x1). The fabric (10) therefore also comprises at least one unreinforced zone (30a, 30b). Due to the bonding between the fibers and / or filaments, the elongation of the reinforced area (20a, 20b, 20c, 20d) resulting from a given force acting in the longitudinal direction of the fabric (10) is less than the elongation of the unreinforced area when subjected to the same force. Such a fabric (10) is particularly useful for manufacturing a laminated assembly.
