An integrally bladed rotor hub and attachment for a turbomachine, comprising:
- a non-metallic rotor hub extending between a first and second axial side, the non-metallic rotor hub including a lip extending around central opening;
- a metallic shaft extending through the central opening;
- and
- a clamp coupled with the shaft, the clamp including a first clamp member arranged on the first axial side of the non-metallic rotor hub and a second clamp member arranged on the second axial side of the non-metallic rotor hub, the first clamp member and the second clamp member engaging the lip such that the non-metallic rotor hub is rotatable with the metallic shaft.
