Method for producing stiffened hollow structure composed of fiber-reinforced composite

摘要

A method for efficiently producing a stiffened hollow structure from a first skin member (4a), a second skin member (4b) and a stiffener (6) each made of a fiber-reinforced composite with reduced steps, the stiffened hollow structure comprising a hollow skin portion (4a,4b) and a stiffening portion (6) for strengthening the hollow skin portion from the inside. The method comprises the steps of: (1) disposing the first skin member and the second skin member on the stiffener, an adhesive (5a,5b) being provided between the stiffener and each of the first skin member and the second skin member; (2) placing a band (1) on the outer surface of the first skin member and the second skin member; and (3) setting the adhesive while tightening the band and applying a tensile force to the first skin member and the second skin member.
