Abstract
A pressure vessel includes a liner having an end wall assembly formed by connecting two rigid end wall members at a fixed distance from each other by a connecting member, and an elastic peripheral wall sheet fixed to the two end wall members so as to enclose a space between them. The two end wall members are made of aluminum alloy by an extrusion process. The connecting member is a pipe made of aluminum alloy by an extrusion process and having a large number of communicating holes in the pipe wall. The peripheral wall sheet is made of aluminum foil and is formed in a cylindrical shape so as to enclose the space between the two end wall members. Around the liner are provided a helical reinforcing layer and a hooped reinforcing layer which are both made of FRP. This pressure vessel is lightweight and can be easily produced at a low cost.
