<P>PROBLEM TO BE SOLVED: To improve the reliability of a high pressure tank that includes a fiber reinforced plastic layer formed on an outer surface of a liner by filament winding. <P>SOLUTION: A method includes: a step of forming a low-angle helical layer 52 on an outer surface of at least part of each liner dome portion 44 and an outer surface of a liner cylindrical portion 42, a step of forming an inner hoop layer 54 on an outer surface of the low-angle helical layer 52 on the liner cylindrical portion 42, and a step of forming a mixed layer 56 by alternately laminating a low-angle helical layer and an outer hoop layer on an outer surface of the inner hoop layer 54 and low-angle helical layer 52 on each liner dome portion 44. Then, on the liner cylindrical portion 42, 90 (%) or more of the sum of the thickness of the inner hoop layer 54 and the thickness of the outer hoop layer in the mixed layer 56 is arranged within the range of 75 (%) of the fiber reinforced plastics layer adjacent to the liner 40 in a thickness direction of the fiber reinforced plastics layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
