Abstract
Official abstract text for this publication.
A high pressure tank includes two ferrules, a resin liner that covers outer parts of the ferrules at both end parts of the resin liner to fixedly install the ferrules, and a CFRP reinforcing layer formed on an outer surface side of the resin liner and attached to the resin liner at a center of a body part of the resin liner. Two leading end parts of the resin liner covering the outer parts of the ferrules protrude from end openings provided at both end parts of the CFRP reinforcing layer.
First claim
Opening claim text (preview).
What is claimed is: 1. A high pressure tank comprising: two ferrules; a resin liner that covers outer parts of the ferrules at a first end part and a second end part of the resin liner to fixedly install the ferrules, the resin liner comprising an elongated cylindrical region connecting the two ferrules; an adhesive applied onto an outer surface side of the resin liner located at a predetermined range of a center of the elongated cylindrical region; and a CFRP reinforcing layer formed on the outer surface side of the resin liner, wherein the CFRP reinforcing layer is attached to the resin liner with the adhesive such that the resin liner and the CFRP reinforcing layer do not have a part attached to each other except for the attached range at the center of the elongated cylindrical region of the resin liner, and the adhesive is not disposed on the CFRP reinforcing layer and the resin liner, except for the predetermined range of the center of the elongated cylindrical region, wherein a leading end part of the resin liner covering the outer parts of the ferrules protrudes from end openings provided at a first end part and a second end part of the CFRP reinforcing layer. 2. The high pressure tank according to claim 1 , wherein the ferrule includes a cylindrical part penetrating the end opening of the CFRP reinforcing layer and a bottom part connected to the cylindrical part on a side of the elongated cylindrical region of the resin liner and including a diameter larger than a diameter of the cylindrical part, and the bottom part includes serration parts at its outer periphery. 3. The high pressure tank according to claim 2 , wherein a diameter of the end opening of the CFRP reinforcing layer is larger than a diameter of a part of the resin liner.
