Aircraft Water Tank and Manufacturing Method Therefor

摘要

The present technology provides a method for manufacturing an aircraft water tank provided with a hollow body and a fiber-reinforced resin layer covering the hollow body. A blow molding step is performed in which polyolefin resin, a thermoplastic resin exhibiting superior durability against disinfectants, is blow molded to obtain a hollow body. Next, a surface treatment step is performed in which a surface treatment is performed upon the entire surface of the hollow body, thereby improving the adhesiveness of the entire surface. Next, a filament winding step is performed in which reinforcing fibers impregnated with a thermosetting resin are wound around the surface of the hollow body and the outer surfaces of the flanges and heated in order to cure the thermosetting resin, thereby forming the fiber-reinforced resin layer on the surface of the hollow body and the outer surface of the flanges.

1. A method for manufacturing an aircraft water tank provided with a hollow body and a fiber-reinforced resin layer covering the hollow body, the method comprising:
a blow molding step of blow molding a polyolefin resin to obtain the hollow body; a surface treatment step of surface-treating the entirety of a surface of the hollow body to improve adhesiveness across the entirety of the surface; and a filament winding step of winding reinforcing fibers impregnated with a thermosetting resin around the surface of the hollow body following the surface treatment step and heating the fibers to cure the thermosetting resin and form the fiber-reinforced resin layer on the surface of the hollow body.
