A tank for storing a pressurized gas including walls of a layered material 15 and continuous fibrous bundles of fibers (16) woven through the walls of layered material (15). The continuous fibrous bundles (16 and Fig. 8) have first ends (17) that extend over a first wall of material (15), pass through the first wall of material (15), extend through the interior of the tank (11), pass through another wall of the material (15) and have second ends (17) that extend over the other wall of the material (15). Other bundles of fibers (18, 20) can be woven between different walls of the tank (11) in a similar pattern to produce complex three dimensional shapes (Figs. 3-8). In another embodiment (Fig. 9), a reinforced composite structure (29) is formed by opposed layers of material (30, 32) extending over a core (28) and continuous bundles (34) are woven in a repeating pattern through the opposed layers (30, 32) and the intermediate core (28) to form the reinforced composite structural member (29).

Réservoir de stockage de gaz pressurisé comprenant des parois faites d'un matériau en couches (15) et de faisceaux de fibres continues (16) tissés à travers les parois du matériau en couches (15). Les faisceaux (16 et fig. 8) ont chacun une première extrémité (17) qui passe à travers la première paroi de matériau (15), traverse l'intérieur du réservoir (11), passe à travers une autre paroi de matériau (15); ces faisceaux comportent une seconde extrémité (17) qui se prolonge au-delà de l'autre paroi de matériau (15). D'autres faisceaux de fibres (18, 20) peuvent être tissés à travers différentes parois du réservoir (11), de la même façon, pour produire des formes tridimentionnelles complexes (fig. 3-8). Dans une autre version (fig. 9), une structure composite renforcée (29) est obtenue au moyen de couches opposées de matériau (30, 32) s'étendant sur une âme (28) et des faisceaux de fibres continues (34) sont tissés selon un motif répété à travers les couches opposées (30, 32) et l'âme intermédiaire (28) afin de former un élément structural composite renforcé (29).
