A pressure vessel liner 1 comprising a tubular trunk 2 and head plates 3, 4 for closing the opposing end openings of the trunk 2. The pressure vessel liner 1 comprises a first liner component 5 providing a trunk 2 and two second liner components 6 and 7 providing two head plates 3 and 4. . The first and second liner components 5, 6, 7 have reinforcement walls 9, 13, 14 inside the peripheral walls 8, 11, 12, respectively, and the reinforcement walls 9, 13, 14) face each other at the corresponding position. Each adjacent pair of liner components 5, 6, 7 has its reinforcing walls 9, 13, 14 joined in a corresponding relationship. The liner 1 has increased pressure resistance with respect to the longitudinal direction. |
