AI Technical Summary
Technical Problem
Existing methods for manufacturing pressure vessels, such as those described in Patent Document 1, are hindered by time-consuming winding and heating processes, which impede productivity improvements.
Method used
A method involving the arrangement of a nozzle-forming member and a cylindrical member made of prepreg material within a mold, followed by inflating a bag-shaped tube to shape the container body, eliminating the need for winding and separate heating steps.
Benefits of technology
This approach enhances productivity by streamlining the manufacturing process, allowing for efficient formation of the pressure vessel without winding or additional heating, thus improving overall production efficiency.

Abstract
To provide a method for manufacturing a pressure vessel and a pressure vessel that can improve productivity. [Solution] A method for manufacturing a pressure vessel 1 comprising a container body and a nozzle 2a connected to the container body, comprising: an arrangement step of arranging a cylindrical member 20 made of prepreg material and a nozzle forming member 2 on which the nozzle 2a is formed inside a mold 10; and a forming step of expanding a silicone tube 30 placed inside the cylindrical member 20 inside the heated mold 10 to shape the cylindrical member 20 and form a container body fixed to the nozzle forming member 2.
