An integral component of a vehicle body includes an open profiled element and a reinforcing rib structure disposed in an interior of the open profiled element. The open profiled element has a fiber-plastics composite body having a first structure, and at least one reinforcement panel from metal for the localized reinforcement of the profiled element. The reinforcing rib structure is produced from a fiber-plastics composite having a second structure.

Integral component of a motor vehicle frame

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&#xb0;, and the fibers of the fiber-plastics composite tier in relation to the preferred connection flange direction enclose an angle b=0 to 30&#xb0;.
