A pressure vessel 100 comprises front and rear end plates 1A, 1B and a plurality of open-ended vessel structures 2A, 2B constructed of fibre-reinforced polymer matrix composite material. The open-ended vessel structures 2A, 2B are positioned adjacent to one another so that their longitudinal axes are parallel to a longitudinal direction extending between the front and rear end plates 1A, 1B, and the open-ended vessel structures 2A, 2B are closed by the front and rear end plates 1A, 1B. An outer reinforcement 3 comprising polymer matrix composite material with continuous fibres extending longitudinally around the pressure vessel 100 secures the front and rear end plates 1A, 1B to the vessel structures 2A, 2B. At least one of the vessel structures 2A, 2B has a partially curved cross section in a plane perpendicular to its longitudinal axis, such that one or more crevices 4 are formed between the vessel structures 2A, 2B, running longitudinally between the front and rear end plates 1A, 1B. The front and rear end plates 1A, 1B are shaped to allow the outer reinforcement 3 to at least partially fill the one or more crevices 4 between the vessel structures 2A, 2B.

The invention relates to a pressure vessel for storing fluids under pressure, using at least one first pole cap, said pole cap having a substantially axially extending region and being connected to at least one further vessel element by means of at least one reinforcing winding of at least one tape. Said tape overlaps the axially extending region of the pole cap and a region of the further vessel element at least to some extent. According to the invention, the pressure vessel is manufactured while using at least one first pole cap and one further vessel element, the first pole cap and the further element being positioned relative to each other to align with each other and relative to a longitudinal axis and then being provided, at least in some regions, with a reinforcing winding that overlaps the first pole cap and the further vessel element at least in some regions thereof.

Disclosed is a method for manufacturing gas cylinders. The disclosed method for manufacturing gas cylinders comprises: a) a step of producing a liner using a liner blower machine; b) a step of applying an adhesive to the threads of the produced liner; c) a step of coupling a bushing to the threads of the liner; d) a step of leaving the liner having undergone step c) for 30 minutes to 2 hours at room temperature so as to naturally harden the adhesive; e) a liner-flaming step of heat-treating the outer surface of the liner with plasma; f) a step of coupling a shaft to the liner; g) a winding step of mixing multiple fiberglass strands with a resin and a hardening agent, and wrapping the mixture around the outer surface of the liner; h) a dry-hardening step of drying the cylinder made of the composite material and having undergone the winding step for 70 to 90 minutes at a temperature of 70°C to 90°C; i) a cooling step of leaving the cylinder made of the composite material for 15 to 40 minutes at room temperature so as to lower the surface temperature of the cylinder having undergone the dry-hardening step to a level of 35°C or lower; j) a step of separating the shaft from the cylinder made of the composite material; k) a step of assembling a valve to the bushing installed in the cylinder made of the composite material; and l) a step of checking the state of the gas cylinder including the cylinder made of the composite material.
