Abstract (en)

[origin: EP2581638A1] A high-pressure tank configured to store a fluid includes: a liner; and a fiber-reinforced resin layer configured to include a fiber and to cover surface of the liner. The liner includes: a cylindrical liner portion in a cylindrical shape; and dome liner portions in a dome shape connected with respective sides of the cylindrical liner portion, each dome liner portion being connected with the cylindrical liner portion, such that an outer surface of the dome liner portion is inclined at a predetermined angle to an outer surface of the cylindrical liner portion. The fiber-reinforced resin layer includes a hoop layer formed on the outer surface of the cylindrical liner portion to cover the outer surface of the cylindrical liner portion and provided by hoop winding that winds the fiber substantially perpendicularly to a central axis of the cylindrical liner portion. The hoop layer is formed, such that an outer surface of the hoop layer has a smaller angle than the predetermined angle to the outer surface of the dome liner portion at a boundary between the hoop layer and the dome liner portion.
