Abstract
In a high-pressure tank including a reinforcement layer and a protective layer, using the same resin for the reinforcement layer and the protective layer is likely to cause bubbles produced in the course of curing the resin to remain on the surface of the tank. There is also a possibility that cloudiness occurs on the surface of the tank during the use of the high-pressure tank. There is accordingly provided a high-pressure tank, comprising a liner; a reinforcement layer formed on the liner and including a thermosetting first resin and a fiber; and a protective layer formed on the reinforcement layer and including a thermosetting second resin. A second gelation temperature that is a gelation temperature of the second resin is higher than a first gelation temperature that is a gelation temperature of the first resin. A viscosity of the second resin is lower than a viscosity of the first resin at the first gelation temperature.
