Method for manufacturing a hollow shaft with at least one integral flange made of fiber composite
First Claim
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; and
after 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.

Abstract
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.
