Abstract

See full text

A method for producing a component made of fiber composite material includes sewing a plurality of reinforcing-fiber layers together using a thread to create a seam and to form at least one reinforcing-fiber preform, wherein the seam has a predetermined thread tension and the sewing pre-compacts the reinforcing-fiber preform to a pre-compacting size. The at least one reinforcing-fiber preform is placed into an injection mold. A final compacting of the reinforcing-fiber preform to a final compacting size is performed by closing the injection mold, wherein the final compacting includes relaxing the thread tension of the seam. A resin is injected into the injection mold and the resin is cured. In addition, an intermediate product includes at least one reinforcing-fiber perform.
