Studies on the development of composite repair techniques through additive manufacturing for aerospace parts using circular manufacturing strategies

Composites are versatile materials widely used in aerospace structures thanks to their excellent mechanical properties. Like all materials, they are sensitive to impact and wear under operating conditions. In the event of damage, instead of replacing the part, repair is an economically feasible alternative, as it increases the product life cycle and also significantly reduces costs. In this project, composite repair techniques are analyzed for optimization and efficiency, where unconventional machining strategies are applied for machining the damaged area, patch manufacturing is undertaken using 3D printing, and integration studies are envisaged to verify the effectiveness of repaired versus blank samples. This project serves greatly within the circular economic framework in the efficient use of resources and the improvement of product life cycles.
