Abstract: The invention relates to a fiber-reinforced pressure vessel (1) and to a method (100) of manufacturing the same, having an inner vessel (2) made of a thermoplastic material for receiving a filling medium, with an outer face and a fiber composite layer (3) arranged around the outer face for providing pressure resistance of the pressure vessel and at least one valve connection (4) connected to the inner vessel and the fiber composite layer; a thermoplastic band (5) being applied additionally at least on a portion of the outer face of the inner vessel, the thermoplastic band having a thermal expansion coefficient which is small enough to keep any gap (6) which may be created by thermal shrinkage between the fiber composite layer and the inner vessel by its thermal expansion coefficient smaller than would be the case without the presence of the thermoplastic band.
