  • Patent number: 11333300
    Abstract: A high pressure tank is provided. The high pressure tank provides improved strength and stiffness by optimizing a laminating pattern and a structure of a fiber reinforced plastic that forms a dome portion of the high pressure tank used in a fuel tank of a fuel cell vehicle. The fiber reinforced plastic having relatively high strength is mixed and used for a weak portion of a dome portion of a support layer of a high pressure tank where stress caused by internal pressure of the high pressure tank is concentrated. In particular, bursting strength and stiffness is increased. The usage amount of the fiber reinforced plastic, the number of windings and a thickness by directly reinforcing a weak point of the dome portion are reduced. Accordingly, manufacturing costs of the high pressure tank are reduced.
