Abstract
The present invention relates to a production method for a workpiece composed of a fiber-composite material, having the following steps: at least one support means is provided. A main material composed of a pre-impregnated fiber semi-finished product and/or of a secondary material are/is applied to the at least one support means in order to form at least two blank-mold areas, in such a manner that at least one of the at least two blank-mold areas has the main material, and at least one of the blank-mold areas has the secondary material. The blank-mold areas are pressure-bonded to one another to form a workpiece blank such that the at least one support means is provided on a surface of the workpiece blank. The at least one support means and the secondary material are removed from the workpiece blank in order to form the workpiece.
