Abstract
A non-woven sheet (10) comprises at least one zone of reinforcement (20a, 20b, 20c, 20d) in which fibers and/or filaments constituting the sheet are bonded together in a reinforcing pattern (22) comprising a plurality of geometric shapes (24), the zone of reinforcement extending over the entire length (L) of the sheet measured in the longitudinal direction (X1), and over a width (l1, l2) strictly less than the width (l) of the sheet (10) measured in a lateral direction (Y1) orthogonal to the longitudinal direction (X1). The sheet (10) thus further comprises at least one non-reinforced zone (30a, 30b). Because of the bonding between the fibers and/or filaments, the elongation of the reinforced zone (20a, 20b, 20c, 20d) under the effect of a given force exerted in a longitudinal direction of the sheet (10) is less than the elongation of the non-reinforced zone under the effect of the same force. Such a sheet (10) may be used in particular for fabricating a laminated assembly.
