The GENEX project has developed an integrated ecosystem of advanced technologies to improve the manufacturing, monitoring, maintenance, and repair of composite aircraft structures, with a strong focus on digitalisation and sustainability.
In manufacturing, a “Manufacturing-for-Performance” strategy was validated using Automated Tape Laying (ATL) for both thermoset (3R resin) and thermoplastic (PEKK) materials. Embedded sensors (fiber optic and piezoelectric) were successfully integrated, enabling structural health monitoring from the production stage. Progress was made in material state control using THz spectroscopy and in multi-physics simulations to support future AI-driven optimisation. A key achievement is up to 70% energy savings through out-of-autoclave processes, although manufacturing costs remain higher than current benchmarks. All developments were validated in an integrated manufacturing cell.
In the area of Health and Usage Monitoring & Management (HUM&M), GENEX developed a multimodal approach combining sensor networks, wireless nodes, and advanced simulation and AI models capable of predicting delamination with up to 90% accuracy. Due to regulatory constraints, the focus shifted to on-ground inspection, still enabling condition-based maintenance. This approach is expected to reduce inspection costs, increase aircraft availability, and minimise downtime.
For repair, innovative digital tools were developed, including the Visual Assistance System (VAS), which combines 3D scanning and real-time projection to guide technicians, improving precision, traceability, and efficiency; portable LIBS for contamination detection and cleaning; hot bonding process digital twin for cost-effective repair planning and online process control; and Smart Patch Repair, with sensing and crack arresting features in bondlines, which requires further maturation. Altogether, these solutions show potential to reduce repair time by up to 30%.
Finally, a Digital Twin Framework was designed and implemented, enabling the creation and operation of digital twins connected to real data across the lifecycle. The system, along with the individual processes, was successfully validated through demonstrators. Overall, GENEX contributes to a more efficient, digital, and sustainable aviation industry.
