摘要

A composite pressure vessel liner suitable for use in a composite pressure vessel for storing high-pressure hydrogen is provided. The composite pressure vessel liner is made of a steel material including: a predetermined chemical composition; and a metallic microstructure in which an area fraction of martensite at a position of ¼ of a wall thickness on an inner side is 30% or more, a total area fraction of martensite and bainite at the position of ¼ of the wall thickness on the inner side is 95% or more, and a total area fraction of martensite and bainite in a wall thickness center part is 95% or more, wherein the composite pressure vessel liner has a wall thickness of 20 mm or more in a longitudinal center part, and a tensile strength of 850 MPa or more in the wall thickness center part.
