Abstract
A composite tank that can suppress electrification, corrosion and strength degradation, a wing comprising the composite tank, and a method for manufacturing the composite tank. The composite tank comprises: a tank body inside which a combustible material is stored, having a first resin portion () formed from a fiber reinforced resin and a metal portion formed from a metal material, a second resin portion () formed from a fiber reinforced resin, which covers at least those regions on the inner surface of the tank body where the first resin portion () adjoins the metal portion, and a plurality of conductive portions () that enable charge transfer through the second resin portion (), from the surface that contacts the combustible material to the first resin portion (), wherein the fiber in the second resin portion () has a higher electrical resistivity than fiber in the first resin portion (), and the second resin portion () forms a layer that isolates the first resin portion () from the metal portion.
