Abstract
A method for producing a body structure composed of a stiffened panel of a fiber-reinforced composite, wherein (a) a skin member is placed on a forming tool, (b) a plurality of preformed stringer members are arranged on the skin member at predetermined intervals, (c) a plurality of preformed outer frame members are arranged on the skin member to intersect the preformed stringer members, (d) the skin member, the preformed stringer members and the preformed outer frame members are integrally hardened by heating under a pressure to prepare an assembly having a skin, stringers and an outer frame, (e) an inner frame member hardened by heating under a pressure beforehand is put into contact with the outer frame, and (f) the inner frame member and the assembly are adhesive-formed by heating under a pressure. A body structure produced by the method is also provided.
