Abstract

A motor vehicle body assembly includes a composite structural component having a connection flange, and a metallic body component or functional group having a connection flange. The connection flange of the composite structural component and the connection flange of the metallic body component or functional group bear on one another and extend substantially across a preferred connection flange direction. The composite structural component has at least one carbon fiber-plastics composite tier having a thermal expansion behavior that in the fiber direction is almost temperature-neutral, and at least one fiber-plastics composite tier having a thermal expansion behavior similar to that of metal. The carbon fibers of the carbon fiber-plastics composite tier in relation to the preferred connection flange direction enclose an angle a=30 to 60°, and the fibers of the fiber-plastics composite tier in relation to the preferred connection flange direction enclose an angle b=0 to 30°.
