    摘要： The invention relates to a rod-shaped fiber composite material (400) composed of a matrix (412) and a circular braid (402) embedded into the matrix. To increase the stability of the fiber composite material (400) and also to perform ducting functions for electricity and fluids, the wall of the circular braid is provided with wall chambers (408) which are separated by a phase boundary from the matrix (412) of the fiber composite material (400). These wall chambers (408) lead to inner and outer sections of the wall of the circular braid (402) being spaced apart, which is useful for the stability with regard to flexing and torsional loading in particular. Rod-shaped fiber composite materials (400) according to the invention can be used for creating stable structural components as well as for producing efficiently protected ducts. The invention further relates to an apparatus and a process which are useful for producing fiber composite material according to the invention.

    摘要： The present invention provides a structural element, in particular for an aircraft or spacecraft, comprising a core, the material density of which varies, at least in portions, in order to optimize the natural vibration behavior of the structural element. The present invention further provides a method for producing a structural element, in particular for an aircraft or spacecraft, comprising the following steps: providing a structural element which has a core; determining the natural vibration behavior of the structural element; and varying the material density of the core of the structural element, at least in portions, in such a way that the natural vibration behavior of the structural element is optimized. The present invention provides still further an aircraft or spacecraft and a rotor blade, in particular for a wind turbine, comprising such a structural element.

    摘要： An apparatus for draping knitted fiber fabrics for curved profiled structural parts of fiber composite material includes a mold having a mold surface that corresponds to a portion of the desired profile geometry and curvature of the profiled structural part, a clamping device for tensioning a layer of a knitted fiber fabric along a tensioning line in a prestressed state, and a movement device for producing a relative movement between the mold and the clamped-in fabric layer such that the mold surface moves close to the fabric layer in a direction perpendicular to the tensioning line and, in the further course of the relative movement, pushes through the tensioning line such that the fabric layer completely covers the mold surface. The clamping device is equipped to load the fabric layer during the entire draping operation with a tensile force acting along the tensioning line.
