A method for manufacturing a radial shaft of a gas-turbine engine which is made up of +/&#x2212;45&#xb0; layers, zero layers and +/&#x2212;30&#xb0; layers of carbon fiber composite and connected to load-input end pieces via sinusoidal connecting areas.

Method for manufacturing a shaft of a gas-turbine engine, in particular a radial shaft or a shaft arranged at an angle to the machine axis

A drive shaft, in particular a radial shaft for a gas-turbine engine, includes a metallic and hollow shaft shankwith load transfer elementsintegrally formed onto its ends. The shaft shankincludes a metal tubeprefabricated as a semi-finished part, designed only for transmission of torsional loads and having a constant wall thickness. An outer or inner reinforcementintended only for ensuring the necessary bending stiffness is provided on the outer and/or inner circumferential surface of the metal tubeand made from a fiber-composite layer' with fibers oriented in the longitudinal direction of the drive shaft. The inner fiber-composite layeracting as outer reinforcementis sheathed with an outer fiber-composite layermade from fibers oriented at an angle of 60&#xb0; to 90&#xb0; relative to the longitudinal direction.
