1. 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 the shaft has a constant cross-section over its length, where a first inner layer forms the sinusoidal inner profile and consists of fibers arranged at ±30° to ±60°, in particular ±45° relative to the axial direction of the shaft, where the concave outer areas of the first layer are filled with fibers parallel to the center axis by means of a second layer in order to form a cylindrical outer contour, where the second layer in each case extends in the circumferential direction only in the concave area, where a third layer with fibers arranged at ±20° to ±45°, in particular ±30° relative to the axial direction of the center axis is provided on the second layer and where a fourth layer with fibers arranged at ±80° to ±90°, in particular ±88° relative to the axial direction is provided on the third layer, wherein between the second layer and the third layer, an intermediate layer formed from fibers parallel to the axial direction is arranged and extends over the entire circumference of the shaft. |
