Abstract
A method of producing a barrier layer of a pressure vessel includes applying the barrier layer to a liner and/or to a fiber-reinforced layer of the pressure vessel while a pressure difference between the internal volume and the surroundings of the pressure vessel is being maintained.
Claims14
A method for the production of a barrier layer of a pressure vessel having an internal volume, comprising the steps of:
- generating a pressure difference between the internal volume and an exterior surrounding of the pressure vessel;
- and
- applying the barrier layer to an interior surface of the pressure vessel while the pressure difference is being maintained such that the barrier layer is under compression in one or both of an axial direction and a circumferential direction when the pressure vessel is not pressurized.
