CA 2174771

A multi-axial, three-dimensional fabric and its method of manufacture formed from five yarn systems including warp yarns (12) arranged in parallel with the longitudinal direction of the fabric, a first pair of bias yarns layers (18) positioned on the front surface of the warp yarns and a second pair of bias yarn layers (18) positioned on the back surface of the warp yarns, vertical yarns (16) arranged in a thicknesswise direction of the fabric in a perpendicularly intersecting relationship to the warp yarns, and weft yarns (14) arranged in the widthwise direction of the fabric and in a perpendicularly intersecting relationship to the warp yarns so as to provide a multiaxial, three-dimensional fabric (F) with enhanced resistance to in-plane shear.

Tissu pluriaxial tridimensionnel et son procédé de fabrication. Ledit tissu est formé à partir de cinq systèmes de fils comprenant: des fils de chaîne (12) disposés longitudinalement, une première paire de couches de fils biais (18) disposées à la surface frontale des fils de chaîne et une deuxième paire de couches de fils biais (18) disposées à la surface dorsale des fils de chaîne, des fils verticaux (16) dirigés dans le sens de l'épaisseur du tissu et coupant à angle droit les fils de chaîne, et des fils de trame (14) disposés transversalement et coupant à angle droit les fils de chaîne. Il en résulte un tissu pluriaxial tridimensionnel (F) présentant une résistance accrue au cisaillement dans le plan.
