Beschreibung
Zusammenfassung:	A vehicle roof stiffener includes at least one fiber reinforced polymer (FRP) portion and at least one metal or metal alloy portion. The FRP portion includes at least one transition structure including a metal or a metal alloy. At least some of the fibers of the FRP portion are embedded in the transition structure. The metal or metal alloy portion is secured to the transition structure of the FRP portion. In an example vehicle roof stiffener, the metal portion extends parallel to a longitudinal axis of a vehicle, and the FRP portion extends transverse to the longitudinal axis. The example vehicle roof stiffener may include a front FRP portion, a rear FRP portion, and two metal side portions. The metal side portions and the FRP portions may be joined by welding the transition structures to the metal portions.
