The present disclosure provides a fuel-impermeable structural unit for use as a structural element of a fuel tank, including a multi-plies structure made of one or more composite material and polymers, and, a sealing polymeric film structurally bonded to and coating the entire surface of at least one face of the multi-plied structure. The polymeric film is integrated with an underlying external layer of said multi-plies structure, is impermeable to the fuel, is not reactive with the fuel, and can bind to an adhesive for fixing one or more rigid elements thereto.

Fuel tank

A method for producing structures from composite materials, the method including forming a three-dimensional preform including at least one skin and a plurality of protrusions extending from the at least one skin, folding the three-dimensional preform such that at least some of the plurality of protrusions lie adjacent to either another one of the plurality of protrusions or the at least one skin and applying resin to the folded three-dimensional preform and curing, thereby to produce the structures from adjacent pairs of the protrusions or from some of the protrusions and the at least one skin.
