METHOD FOR MANUFACTURING A TANK FOR THE CONTAINMENT OF A PRESSURISED GAS, IN PARTICULAR HYDROGEN

WIPO Patent Application WO/2022/189470

A1

The invention relates to a method for producing a composite tank having a continuous fibre reinforcement, a prismatic shape and a thickness e, for the storage of a pressurised gas in an internal cavity of said tank, said tank comprising fibres extending between two non-contiguous faces of said tank through the internal cavity. The method is characterised in that it comprises the steps consisting in: (i) obtaining (720) a prismatic fibrous preform having a thickness e comprising three-dimensional continuous reinforcements throughout its thickness; (ii) impregnating (760) an outer layer of said preform with a polymer over a thickness of less than 1/4 of the thickness e so as to constitute a composite outer shell extending over all the faces of the prism; (iii) forming (790) 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.
