A fiber textile semi-finished material is fed directly and reformed onto a carrier and reforming tool, where it is fixed with a binder. The carrier has a contour matching the negative or positive shape of the final required geometry of a preform that is to be fabricated. The reformed semi-finished article fixed with the binder is removed from the carrier to provide the preform. Several preforms of different cross-sectional shapes are joined together, compacted to form a dense component having nearly the required finished contour, impregnated with a matrix system including a curable adhesive resin, and then cured under an elevated temperature and/or pressure. The result is a finished fiber reinforced composite structural element such as an aircraft window frame. This method is carried out on an apparatus including the rotating carrier and reforming tool, which may have a cylindrical and/or annular surface for receiving and reforming the material.
