Composite tank, wing, and method for manufacturing composite tank

摘要

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 (11, 12) formed from a fiber reinforced resin and a metal portion formed from a metal material, a second resin portion (22) 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 (11, 12) adjoins the metal portion, and a plurality of conductive portions (23) that enable charge transfer through the second resin portion (22), from the surface that contacts the combustible material to the first resin portion (11, 12), wherein the fiber in the second resin portion (22) has a higher electrical resistivity than fiber in the first resin portion (11, 12), and the second resin portion (22) forms a layer that isolates the first resin portion (11, 12) from the metal portion.

1. A composite tank comprising:
a tank body inside which a combustible material is stored, the tank body 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 an inner surface of the tank body where the first resin portion adjoins the metal portion, the second resin portion including a combustible-material-contacting surface that contacts the combustible material, and a plurality of conductive portions that are provided within the second resin portion in such a way as to enable charge transfer through the second resin portion, from the combustible-material-contacting surface of the second resin portion through to the first resin portion, wherein fiber incorporated within the second resin portion has a higher electrical resistivity that fiber incorporated within the first resin portion, and the second resin portion forms a layer that isolates the first resin portion from the metal portion, and wherein the conductive portions are portions without the fibers in the second resin portion, are formed solely of the resin, and extend from the combustible-material-contacting surface through to the resin portion.
