Pressure vessel with lifetime value director |
摘要 |
A remaining lifetime of a pressure vessel mounted on a fuel cell vehicle or the like and comprises a liner at its inner side and a reinforcing layer at its outer side can be predicted with high precision and in short time. An artificial imperfect structure is formed at an outer surface of the liner in a size capable of being maintained by a weakest part of a hydrogen gas tank throughout the total period of use of the hydrogen gas tank. A detector is, for example, comprised of a crack gauge intervening between the liner and the reinforcing layer, and is fixed to the outer surface of the liner close to the artificial imperfect structure. A crack length increases accompanying the increase of a pressure cycle of an internal pressure caused by usage of the hydrogen gas tank. The detector increases a resistance value accompanying a crack growth. |
