Official abstract text for this publication.
A high pressure tank has a liner and a reinforcing layer. The reinforcing layer is formed on an outer surface of the liner. An adhesion inhibiting process that inhibits the liner from adhering to the reinforcing layer is applied to at least a portion of the liner in a region contacting the reinforcing layer.
Opening claim text (preview).
What is claimed is: 1. A manufacturing method of a high pressure tank, comprising: forming a reinforcing layer on an outer surface of a liner; and performing an adhesion inhibiting treatment that inhibits adhesion of the liner to the reinforcing layer on at least a portion of a region where the liner contacts the reinforcing layer, before forming the reinforcing layer, wherein the at least the portion of the region is a dome portion which the liner includes, and wherein the dome portion includes a curved surface shape and is provided between the liner and the reinforcing layer so as to contact the reinforcing layer; and wherein specular finishing is applied to the outer surface of the liner, in the adhesion inhibiting treatment. 2. The manufacturing method of a high pressure tank according to claim 1 , wherein the high pressure tank is a high pressure hydrogen tank that is configured to be filled with hydrogen. 3. The manufacturing method of a high pressure tank according to claim 1 , further comprising a cap provided at an end of the liner and including a surface that is inhibited from adhering to the reinforcing layer and being provided between the cap and the reinforcing layer. 4. The manufacturing method of a high pressure tank according to claim 1 , wherein the reinforcing layer is formed by directly winding fiber impregnated with a resin on the outer surface of the liner.
