<p>PURPOSE:To realize lightweight construction of an accumulator which is provided with a spherical shell. CONSTITUTION:Two semispherical cores 2, 3 are formed by thin metal plate, and a sphere is formed by fitting both cores 2, 3 together. The outside of the sphere is wound by means of a thready FRP and an FRP layer 17 is formed, leading to formation of a shell 18 by means of both cores 2,3 and the outside FRP layer 17.</p> |
