A method for producing a composite tank is disclosed. The tank has a continuous fiber reinforcement, a prismatic shape, and a thickness e for the storage of a pressurized gas in an internal cavity of the tank. The tank comprises fibers extending between two non-contiguous faces of the tank through the internal cavity. The method includes: (i) obtaining a prismatic fibrous preform having a thickness e comprising three-dimensional continuous reinforcements throughout its thickness; (ii) impregnating an outer layer of the preform with a polymer over a thickness of less than of the thickness e so as to constitute a composite outer shell extending over all faces of the prism; and (iii) forming a sealed layer constituting an inner lining, having a thickness of less than 1/10th of the thickness e between the outer shell and the fibrous network contained in the cavity of the tank.

Carrier with localized fibrous insert and methods

A structural reinforcement for an article including a carrier that includes: (i) a mass of polymeric material having an outer surface; and (is) at least one consolidated fibrous insert having an outer surface and including at least one elongated fiber arrangement having a plurality of ordered fibers arranged in a predetermined manner. The fibrous insert is envisioned to adjoin the mass of the polymeric material in a predetermined location for carrying a predetermined load that is subjected upon the predetermined location (thereby effectively providing localized reinforcement to that predetermined location). The fibrous insert and the mass of polymeric material are of compatible materials, structures or both, for allowing the fibrous insert to be at least partially joined to the mass of the polymeric material. Disposed upon at least a portion of the carrier will be a mass of activatable material.

Extruded multi-layer molded running board
