Patent ID: 10913565

Abstract:
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.
