Abstract
Official abstract text for this publication.
A fuel tank includes: a tank main body made of a resin material; and a cover member which is formed using threads made of a fiber-reinforced composite material containing a thermoplastic resin fusible to a surface of the tank main body. The cover member has a twill weave structure at least in its portion fused to the upper surface of the tank main body. The threads each have a core-sheath structure in which a fiber made of a polypropylene resin is coated with a polyethylene resin.
First claim
Opening claim text (preview).
1 . A fuel tank comprising: a tank main body made of a resin material; and a cover member which is formed using threads made of a fiber-reinforced composite material containing a thermoplastic resin fusible to a surface of the tank main body, wherein the cover member has a twill weave structure at least in its portion fused to the upper surface of the tank main body. 2 . The fuel tank according to claim 1 , wherein sheets each formed having the twill weave structure are arranged in a plurality of layers in the cover member, and are fused together. 3 . The fuel tank according to claim 1 , wherein as the twill weave structure, the cover member has a multi-twill weave structure in which a plurality of single twill weave sheets are arranged in a plurality of layers, and at least some of warp threads or weft threads of one of the single twill weave sheets facing each other each cross warp threads or weft threads of another of the single twill weave sheets facing each other. 4 . The fuel tank according to claim 1 , wherein the threads each have a core-sheath structure in which a fiber made of a polypropylene resin is coated with a polyethylene resin. 5 . The fuel tank according to claim 4 , wherein the surface of the tank main body is made of a polyethylene resin. 6 . The fuel tank according to claim 2 , wherein the threads each have a core-sheath structure in which a fiber made of a polypropylene resin is coated with a polyethylene resin. 7 . The fuel tank according to claim 6 , wherein the surface of the tank main body is made of a polyethylene resin. 8 . The fuel tank according to claim 3 , wherein the threads each have a core-sheath structure in which a fiber made of a polypropylene resin is coated with a polyethylene resin. 9 . The fuel tank according to claim 8 , wherein the surface of the tank main body is made of a polyethylene resin.
