HARVEST project concept

Development of multifunctional TEG-enabled structural composite materials for the Aeronautics sector

HARVEST project will employ breakthrough technologies combining bio-inspired hierarchical ThermoElectric Energy Generating (TEG) carbon fiber (CF) reinforcements with novel thermoset matrix systems (3R Repair-Recycle-Reprocess technology). The “hierarchical” reinforcement will be comprised from a micron-scale CF coated with nano-scaled particles. The aim is to develop multifunctional TEG-enabled structural composite materials for the Aeronautics sector.

CFs yarns or textiles will be coated with nanomaterials using facile & environmentally friendly deposition and doping methods in a Roll-to-Roll (R2R) pilot line targeting dramatically increased TEG performance compared to existing composites, carbon and organic based materials.


Innovative TEG-hierarchical composites will be manufactured with new generation 3R thermoset matrix systems enabling out of autoclave manufacturing and self-repair. These will be interfaced with a purposely designed hardware to:


(i) power inherent functionalities (e.g. strain, damage or UV exposure sensing),
(ii) drive external elements (e.g. piezo electric sensors for SHM),
(iii) transmit sensing signals to a remote panel.


The autonomous SHM systems will: increase the safety of civil aviation; reduce emissions and maintenance & life cycle costs. The proposed technologies will be finally integrated in two aircraft demonstrator parts, targeting areas with temperature gradients (e.g. engine vs. environment, inside vs. outside fuselage during flight) or where quick heat dissipation is essential (e.g. landing gear after take-off). The location of suitable heat sinks in real structures will be established using advanced numerical tools to identify thermal gradients in operating environment.
