Abstract
A method for performing pressure tests on a composite pressure vessel, including providing a composite pressure vessel with at least one opening an injection of a liquid; injecting the liquid in the composite pressure vessel through the at least one opening to reach a threshold pressure; measuring an external volume variation of the composite pressure vessel; draining the liquid from the composite pressure vessel through the at least one opening; and drying an inside cavity of the composite pressure vessel with a drying gas. The drying the inside cavity of the composite pressure vessel is performed at a pressure inside the composite pressure vessel, which is lower than an external pressure. A device for manufacturing and pressure testing a composite pressure vessel.
