A stabilizer bar or stabilizer link in fiber composite construction is of a monolithic construction without fiber interruption. The cross section geometry, the wall thickness, and the fiber orientation vary in axial direction and radial direction such that the requirements defined by the available construction space and the expected loads are fulfilled. The fiber orientation is adjusted axially and radially load-appropriately. The middle section of the stabilizer bar that is primarily torsion-loaded is reinforced with fibers oriented between +/−35° and +/−55° relative to the longitudinal axis and the end members that are primarily bending-loaded are reinforced with fibers oriented between +/−20° and +/−40° relative to the longitudinal axis. In the transitional areas between the middle section and the end members there are transitions between these fiber orientations relatively to the longitudinal axis.
