A method for efficiently producing a stiffened hollow structure from a
first skin member, a second skin member and a stiffener each made of a
fiber-reinforced composite with reduced steps, the stiffened hollow
structure comprising a hollow skin portion and a stiffening portion 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 being provided between the
stiffener and each of the first skin member and the second skin member;
(2) placing a band 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.
