GMI AERO has developed over twenty five (25) years thorough knowledge of composite structures manufacturing and repair processes for the aircraft industry, offering to the manufacturers, airlines and maintenance centres a complete range of control equipment and instrumentation, engineering solutions, training and field assistance services. GMI developed and continuously upgrades a series of portable composite repair equipment for all the steps which need to be followed for the performance of a “typical” bonded composite repair (NDT of the damaged area, removal of the damaged composite material by cutting / drilling / milling and composite patch preparation / application, including preparation of vacuum bagging and application of heat), fulfilling the repair specifications requirements and overcoming the numerous constraints of repair performance within hangars or repair workshops. Most of this equipment is proposed in the Structural Repair Manuals (SRMs) of major aircraft manufactures (Airbus, Boeing, ATR).

Research is conducted specially in the field of the repair, maintenance and health monitoring of composite structures, including the design of innovative tooling and equipment for aircraft structures. GMI, in cooperation with RTDs, has performed extensive R&D activities in the field of structural health monitoring, using Optical Fibre Bragg Grating (OFBG) sensors, mainly targeting to the post-repair structural health monitoring of aircraft components. GMI AERO has established co-operation with major aircraft manufacturers and higher education institutes. Agreements for advanced repair equipment and technology solutions have been settled with Airbus, ATR, Dassault, Boeing, Bombardier, while GMI has performed applied research activities in numerous EU research projects in the field of bonded composite repair, structural health monitoring and induction heating.

Role in the project

GMI is a leading company in the field of composite maintenance and repairs, with extensive research experience in the field of developing solutions for in situ heating, NDT and health monitoring of composite structures, with numerous applications and publications in the area. GMI has a practical experience of needs in this field, from experience with its worldwide panel of airline customers. The main role of GMI will be leading of definition of test scenarios, sample preparation and overview of sample measurements WP, performance of “baseline” NDT measurements, manufacturing of specimens using state-of-the-art techniques, development of health monitoring methodologies and techniques using magnetostrictive sensors and demonstration of ENDT techniques in real-life repair environment.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 636494.

This project is endorsed by the European Aeronautics Science Network - EASN.
