Triumph Group and Embraer have joined hands to develop and demonstrate the airworthiness of a thermoplastic primary structure in flight. Triumph Aerospace Structures has been developing a thermoplastic elevator assembled using induction welding. Embraer will integrate the thermoplastic elevator structure in an aircraft platform and carry out in-flight tests.

Testing will demonstrate the technology readiness of the structure. The primary detail parts for the elevator structure will be made of unidirectional carbon reinforced thermoplastic material, a first for the industry.

"Triumph has made great progress in the innovation of thermoplastic structure joining," said Dave Dennison, vice president of Engineering for Triumph Aerospace Structures. "We are excited to demonstrate the major leap in the technical maturity we have developed in large thermoplastic primary structures and induction welding."

Embraer will integrate the thermoplastic elevator structure in an aircraft platform and perform in-flight tests to demonstrate the technology readiness.

"Working with Triumph to achieve a certifiable component has been a rewarding experience. Thermoplastics manufacturing and integration can certainly add value to our products, said Richard S Oliveira, composites specialist for the Chief Engineering Office, Embraer.

Triumph has made significant investment in thermoplastic technology, and an in-flight testing of the elevator will demonstrate the technology is ready to progress from the lab into production.
