A hybrid component for a gas-turbine engine includes a supporting structure (2) in fiber-composite material and a metallic structure (3) intimately connected to the latter via a thin highly elastic intermediate layer (7) made of thermoplastic polyurethane. The highly elastic material not only provides for a firm connection between the metallic structure and the supporting structure, but also for an absorption of the in-service vibrations and a compensation of the different expansion behavior of the fiber-composite material and the metal. Furthermore, a concentrated load applied to the component by an impinging foreign body is converted by the highly elastic intermediate layer into an area load, thereby substantially reducing the hazard of damaging the supporting structure due to crack formation.
