During the three-year project the consortium carried out exploratory research on multifunctional composite materials and implemented an extensive programme of training and knowledge exchange.
The research investigated several approaches for integrating sensing and heating capabilities into composite structures. CNT-doped thermoplastic filaments were studied as potential strain sensors embedded within glass-fibre reinforced polymer composites. Mechanical testing demonstrated that the integration of these filaments does not degrade structural performance while allowing electrical monitoring of deformation.
CNT-doped thermoplastic strips were also investigated as embedded heating elements that can generate controlled thermal fields inside composite structures. These heaters can support non-destructive inspection techniques such as active thermography and can also be used for de-icing applications.
Different methods for integrating piezoelectric sensors into composite laminates were explored to enable structural health monitoring based on guided wave propagation. Experimental studies and numerical modelling investigated the interaction of elastic waves with damage such as cracks and delamination, supporting the development of improved damage detection approaches.
The project successfully produced demonstrator composite structures with integrated sensing and heating elements. Prototype airfoil-shaped components with embedded CNT-based heaters were manufactured and tested under laboratory conditions and in an icing wind tunnel, demonstrating effective anti-icing and de-icing performance.
The project also achieved significant results in capacity building. Twenty-five Polish researchers participated in collaborative research activities with the European partners. Thirty-one research externships and several staff exchanges were organised, allowing researchers to gain experience with advanced manufacturing, testing and non-destructive inspection methods.
Four specialised technical workshops on composite design, production, testing and sustainability were organised for young researchers, while five additional workshops strengthened research management skills, including proposal preparation, project management and intellectual property management.
The research results were disseminated through scientific publications and international conferences. By the end of the project seven research papers had been published, submitted or prepared and sixteen conference presentations had been delivered.
