Abstract

A supporting strut for supporting an intermediate deck (2) that is arranged in an aircraft fuselage (1), includes a hollow cylindrical rod body (3) that includes a fiber reinforced material, with the two ends of the rod body (3) being designed as attachment sections for detachable attachment to the aircraft fuselage (1) or to the intermediate deck (2), wherein the rod body (3) includes at least one first reinforcement layer (10a) made from a carbon fiber fabric with an identical number of warp- and weft threads in 45° alignment or 90° alignment, as well as at least one second reinforcement layer (10b, 10c) made from a carbon fiber fabric including a higher number of warp threads than weft threads in 0° alignment, as well as a final layer including glass fiber, which together with artificial resin form a compact fiber reinforced material.
