A supporting strut for supporting an intermediate deck () that is arranged in an aircraft fuselage (), includes a hollow cylindrical rod body () that includes a fiber reinforced material, with the two ends of the rod body () being designed as attachment sections for detachable attachment to the aircraft fuselage () or to the intermediate deck (), wherein the rod body () includes at least one first reinforcement layer () made from a carbon fiber fabric with an identical number of warp- and weft threads in 45&#xb0; alignment or 90&#xb0; alignment, as well as at least one second reinforcement layer () made from a carbon fiber fabric including a higher number of warp threads than weft threads in 0&#xb0; alignment, as well as a final layer including glass fiber, which together with artificial resin form a compact fiber reinforced material.

An undercritical drive shaft and a method of producing the undercritical drive shaft from fiber composite material is disclosed. The drive shaft, which is produced of fiber composite material and is to be used as an undercritically operating shaft, has a high damage tolerance with respect to resistance to torsion and the manufacturing process requires lower expenditures. For the drive shaft, the fiber composite material consists of several successively individually wound-up webs of prepreg. For the method of producing the drive shaft from fiber composite material, as the fiber material, the web-shaped prepreg is wound onto the winding spindle and this prepreg is deaerated and simultaneously compressed by the winding-on of a thermoplastic woven band which is prestressed in a defined manner. The thermoplastic woven band is unwound again and additional prepreg layers are then wound up which are then deaerated and compressed in the same manner by a thermoplastic woven band.
