Abstract
In a method for manufacturing a composite cross-section member, a continuous steel sheet is fed to a manufacturing device and bent and roll-formed into a predetermined cross-sectional shape, a discontinuous aluminum core is locally inserted at an arbitrary stage of the roll forming, and the steel sheet is bent such that the core and the steel sheet are integrated, to obtain a composite cross-section member.
