A closed ring fiber reinforced frame structure is produced by first preparing a prepreg. A section of the prepreg is formed into a flange preferably after impregnation by folding the flange section along a folding line. The folding line is formed by securing a deformable or drapable fiber ribbon material, for example by sewing or stitching to a carrier substrate which is preferably also a fiber material. The sewing seam or stitching line becomes the folding line. The ribbon material is so secured to the carrier substrate that the fiber orientation of the ribbon material is uniformly distributed all around a ring component that is formed of the ribbon material on the substrate. The impregnated ring component with its substrate is then cured after the folding of the flange to complete the ring frame structure.
