Supporting strut for supporting an intermediate deck that is arranged in an aircraft fuselage, and method for producing a rod body for such a supporting strut

摘要

The invention relates to a supporting strut for supporting an intermediate deck (2) that is arranged in an aircraft fuselage (1), comprising a hollow cylindrical rod body (3) that comprises a fibre reinforced material, with the two ends of said 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) comprises at least one first reinforcement layer (10a) made from a carbon fibre 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 fibre fabric comprising a higher number of warp threads than weft threads in 0° alignment, as well as a final layer comprising glass fibre, which together with artificial resin form a compact fibre reinforced material.
