<P>PROBLEM TO BE SOLVED: To create a supporting strut whose rod body features a lightweight construction while at the same time providing good buckling resistance and resistance to damage as well as providing improved fire-resistance characteristics. <P>SOLUTION: The 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 fibre 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 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 including a higher number of warp threads than weft threads in 0° alignment, as well as a final layer including glass fibre, which together with artificial resin form a compact fibre reinforced material. <P>COPYRIGHT: (C)2010,JPO&INPIT |
