A rod for supporting components in a fuselage cell structure, in particular produced with fibre-reinforced composite materials, of an aircraft, in particular for supporting at least one floor frame on at least one annular former and/or at least one further component of the fuselage cell structure. In accordance with the invention the rod is formed, at least in portions, with a metal foam, in particular for the absorption of crash loads. The metal foam can transform, irrespective of its inherent weight, the high mechanical loads produced in the event of an accident into work of plastic deformation at the microcavities within the metal foam. A first variant of the rod is almost completely formed by a metal foam, whereas a second embodiment comprises merely a core made of the metal foam with a relatively small diameter, which core is surrounded coaxially by a support casing and an outer sleeve.
