Abstract

See full text

A shaft of a turbine engine made from fiber-composite material, having a sinusoidal inner profile which extends over the entire length of the shaft on its inner wall, where a first inner layer forms the sinusoidal inner profile and has fibers arranged at ±45° relative to the axial direction, where the concave outer areas of the first layer are filled with fibers parallel to the center axis by a second layer to form a cylindrical outer contour. The second layer extends in the circumferential direction only in the concave area. A third layer with fibers arranged at ±30° relative to the axial direction is provided on the second layer A fourth layer with fibers arranged at ±88° relative to the axial direction is provided on the third layer. An intermediate layer is formed between the second and third layers from fibers parallel to the axial direction.
