For a method for manufacturing a hollow shaft with at least one integral flange made of fiber composite, a plurality of intersecting windings of fiber material are applied onto a core. Moreover, the core has, for each flange, a radial spreader ring with an axial bearing surface. The windings are laid over an outer circumferential portion of the respective spreader ring and fixed. One or several inserts made of fiber material are inserted in the area of the spreader ring between the windings. The fixing of the wound fiber material is released, but is first still held on the spreader ring. Portions of the windings are then pulled off from the outer circumferential portion of the spreader ring and brought to rest on the axial bearing surface of the spreader ring in order to form a partial portion of a flange.

1. Method for manufacturing a hollow shaft with at least one integral flange made of fiber composite comprising: depositing a plurality of intersecting windings of fiber material onto a core which represents the inner contour of a shaft portion, the core having for each flange a radial spreader ring with an axial bearing surface for defining the shape of a front wall of the flange;laying and fixing the windings over an outer circumferential portion of the respective spreader ring such that the windings form a gusset between the spreader ring and a substantially cylindrical surface of the core; andafter the finishing of the windings, releasing the fixing of the wound fiber material and pulling off portions of the windings from the outer circumferential portion of the spreader ring over an edge of the spreader ring by means of a stripper wherein the stripper impinges the gusset, laying the fiber material of the gusset against the substantially cylindrical surface of the core as well as against the bearing surface of the spreader ring and wherein the fiber material is brought to rest on the axial bearing surface of the spreader ring thereby forming a partial portion of a flange. 2. Method according to claim 1, wherein after the finishing of the windings and before the releasing of the fixing of the wound fiber material, a circumferential layer is applied onto portions of the windings on the outer circumferential portion of the spreader ring for compacting and stabilizing the wound fiber material. 3. Method according to claim 1, wherein the stripper is displaced in direction of the bearing surface of the stationary spreader ring and acts on a gusset of the windings which is formed between the spreader ring and the shaft portion of the wound fiber material. 4. Method according to claim 1, wherein a spreader ring is used, the outer diameter of which increases in direction of the shaft portion of the wound fiber material or of the shaft. 5. Method according to claim 1, wherein one or several inserts are used, the total thickness of which increases in direction of a fiber material end on the spreader ring. 6. Method according to claim 1, wherein one or several inserts are used, the thickness of the one or several inserts is adapted in such manner that the corresponding flange has a constant wall thickness. 7. Method according to claim 1, wherein one or several inserts in the form of ring disk segments are used. 8. Method according to claim 1, wherein a stitched insert in the form of a ring disk is used. 9. Method according to claim 1, wherein one or several stitched ring disks are used as inserts, which have an outwards increasing material thickness. 10. Method according to claim 1, wherein one or several stitched ring disks are used as inserts, which have a deposit angle (α) increasing from the inner side to the outer side, the deposit angle (α) being defined as an angle between the fiber orientation on the ring disk and its radial direction. 11. Method according to claim 1, wherein the length of the hollow shaft is predetermined by a multipart core which has a cylindrical portion for predetermining the inner contour of a shaft portion and a spreader ring displaceable with respect hereto for defining the form of the front wall of a flange. 12. Method according to claim 1, further comprising placing one or several inserts made of fiber material in the area of the spreader ring between the windings.
