Abstract
The present invention relates to a pressure vessel for storage of solid, liquid and/or gaseous media under an operating pressure above atmospheric pressure, wherein the pressure vessel encloses a hollow space provided for storage of the medium, and is provided with at least one connector for loading and/or unloading. Because the pressure vessel is composed at least in part of a tube that in turn is manufactured from a fiber-reinforced thermoplastic, wherein the thermoplastic material contains more than 10% by volume of fibers with an average fiber length over 50 mm, the pressure vessel has a low weight and a very good resistance to corrosion and resistance to chemically aggressive media, yet it nevertheless withstands the mechanical stresses of the normal high operating pressures up to 25 Mpa.
