Abstract:
1. A method of manufacturing a body structure for a motor vehicle including the steps of: producing one or more reinforcing members by providing an elongate core of a relatively high yield strength metal, a casing of a relatively low yield strength metal, the casing having a constant section profile with a pair of spaced flanges and an internal wall defining a closed section cavity; placing the core within the cavity; co-drawing the core and the casing through a die to bind the casing to the core; producing one or more panel members each having a pair of spaced flanges corresponding to the spaced flanges on the reinforcing member; connecting at least one reinforcing member and at least one panel member at the spaced flanges to form structural members; providing at least one or more body panels; attaching the structural members and the body panels together in a predetermined arrangement to produce the body structure wherein the core is a profiled flat strip, being non-planar in cross-section and having two longitudinally extending edges; wherein the material forming the longitudinal edges is bent back on itself to form double-thickness end sections.
