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.
Claims12
A method for manufacturing a composite cross-section member, the method comprising:
- feeding a continuous metal strip to a roll former for bending and roll forming the metal strip into a predetermined cross-sectional shape;
- locally inserting a discontinuous light-metal core at an arbitrary stage of the roll forming;
- and
- bending the metal strip so as to integrate the core and the metal strip and obtaining a composite cross-section member,
- wherein the discontinuous light-metal core has a predetermined length that is equal to or smaller than a length between an adjacent pair of rolls of the roll former.
