Abstract: A drive shaft, in particular a radial shaft for a gas-turbine engine, includes a metallic and hollow shaft shank 1 with load transfer elements 2, 10, 11 integrally formed onto its ends. The shaft shank 1 includes a metal tube 3, 9 prefabricated as a semi-finished part, designed only for transmission of torsional loads and having a constant wall thickness. An outer or inner reinforcement 5, 8 intended only for ensuring the necessary bending stiffness is provided on the outer and/or inner circumferential surface of the metal tube 3, 9 and made from a fiber-composite layer 13, 13? with fibers oriented in the longitudinal direction of the drive shaft. The inner fiber-composite layer 13 acting as outer reinforcement 5 is sheathed with an outer fiber-composite layer 14 made from fibers oriented at an angle of 60° to 90° relative to the longitudinal direction.

Abstract: Injection molding tool for the manufacture of a plastic element sheathed with a sheet-metal shell (8), where the gate (12) which is designed as an integral part of the lower mold half (9) for correct positioning and supply of the plastic melt projects beyond the inner surface of the mold half (9) into the sheet-metal shell having a positioning opening (14), such that the plastic melt is discharged inside the sheet-metal shell and does not flow past it.
