Abstract
A vehicle roof stiffener includes a metal or metal alloy frame defining a central opening and at least one corner. The vehicle roof stiffener also includes a fiber reinforced polymer (FRP) portion including at least one transition structure comprising a metal or a metal alloy. At least some of the fibers of the FRP portion are embedded in the transition structure. The FRP portion is located in the at least one corner. In some examples, the frame includes an opening in the at least one corner, and the FRP portion spans the opening. In other examples, the FRP portion overlaps the frame at the at least one corner. The FRP portion located at the corner may improve rigidity of the roof stiffener to increase resistance to a racking motion and increase the overall stiffness of the vehicle.
