Abstract:
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.

Claim (Index 18):
A method of forming a curved profiled structural part from a fiber composite material, the method comprising:\n obtaining at least one layer of a knitted fiber fabric with an applied or impregnating binding material,\n applying a tensile stress to opposite ends of the at least one layer of the knitted fiber fabric along a tensioning line that extends through the opposite ends and along a longitudinal direction of the at least one layer of the knitted fiber fabric to tension the at least one layer of the knitted fiber fabric with a tensioning force acting along the tensioning line, \n while maintaining the tensioning force acting along the tensioning line, executing a relative movement between the tensioned at least one layer of the knitted fiber fabric and a mold surface defined by at least one mold until the mold surface pushes through the tensioning line to such an extent that the at least one layer of knitted fiber fabric completely covers the mold surface, wherein the mold surface defines at least a portion of a profile geometry and curvature of the curved profiled structural part, and \n with the at least one layer of knitted fiber fabric completely covering the mold surface, curing the binding material while continuing to maintain the tensioning force acting along the tensioning line to cause the at least one layer of knitted fiber fabric and the binding material to cooperatively yield the fiber composite material fixed in the shape of the mold surface to form the curved profiled structural part.
