Therefore, it is necessary to clarify the fatigue properties of the liner materials in a hydrogen environment.
Thus, it will be important to clarify how the impact properties of the liner materials are affected by hydrogen and fatigue to ensure the safety of high-pressure hydrogen tanks installed in FCVs.
This stress fluctuation is caused by a spherical wave and the structure of the attachment jig, not an inherent phenomenon of the materials [9].
