Abstract:
A rotational body, to a rotor and to a flywheel energy storage unit having such rotational bodies is disclosed and a method for the production of a rotational body, having a cylinder jacket at least partially wound using a fiber-reinforced composite. A cylinder axis includes open cylinder base surfaces, whereby the cylinder jacket, with its inside facing the axis of rotation and its outside oriented in the opposite direction, has a length parallel to the axis of rotation of more than twice the outer diameter of the rotational body, and it has a wall thickness that is less than 12.5% of the outer diameter. The fiber-reinforced composite of the cylinder jacket has a layered structure in the radial direction comprising helical layers of fibers which extend along the axis of rotation and whose orientation along the helical fiber angle is less than 35° relative to the axis of rotation.

Claim (Index 24):
A method for the production of an internally hollow cylindrical rotational body according to claim  1  for rotors for flywheel energy storage units with a large energy content, having a cylinder jacket, a cylindrical axis as the axis of rotation, open cylinder base surfaces and a length parallel to the axis of rotation amounting to more than twice the provided outer diameter of the rotational body, comprising the following steps:\n (a) a suitable, appertaining winding mandrel is provided for the manufacture of the rotational body, whereby the cylinder jacket is wound, at least partially, using fiber-reinforced composite; \n (b) helical layers consisting of fibers having an orientation along a helical fiber angle between 15\u00b0 and 30\u00b0 relative to the axis of rotation and circumferential layers consisting of fibers having an orientation along a circumferential fiber angle greater than 80\u00b0 relative to the axis of rotation are wound alternatingly around the winding mandrel using a suitable winding method until the desired thickness has been achieved for the cylinder jacket amounting to less than 15% of the outer diameter of the cylinder jacket, whereby all of the helical layers are arranged within the inner one-third of the cylinder jacket as seen in the radial direction, the helical fiber angles of the various helical layers differ and the helical fiber angles increase in the radial direction from one helical layer to the next helical layer as the distance from the axis of rotation increases; and \n (c) the fiber-reinforced composite of the rotational body is cross-linked and the winding mandrel is removed from the wound and cross-linked rotational body.
