Abstract

Longitudinal members for motor vehicles may generally include a supporting element that is releasably connectable to an energy absorption mechanism. The supporting element may typically include a joining zone that can be used to secure the supporting element to one or more chassis or drive components of the motor vehicle. The supporting element and the energy absorption mechanism may be comprised of fiber-reinforced plastic. More specifically, the supporting element may be comprised of a plurality of length portions having different fiber orientations. For example, a first length portion may have fibers oriented substantially parallel to a horizontal longitudinal plane about which the supporting element is positioned, whereas a second length portion between the first length portion and the energy absorption mechanism may have intersecting fibers oriented oblique to the horizontal longitudinal plane.
