Composite hybrid structures

Eaton’s expertise in composites engineering, filament winding, and metal-to-composite bonding enable us to design and produce competitively priced composite hybrid structures to meet the most rigorous specifications.

Our composite hybrid structures can be found in a wide range of applications including aspirators for commercial aircraft, military launch tubes and rocket motor cases and we are the world’s leading producer of composite flywheel rims used as an alternate solution for energy storage.

We have the ability to integrate composites with metal components for a total composite solution that can seamlessly combine complex mechanical subassemblies, fittings and joints to our high-performance composite forms. Let our engineers design a custom solution to fit your needs.
