HARVEST aims to develop Aerostructures that will: i) increase aircraft safety and operational efficiency ii) reduce environmental impact. In order to do this, HARVEST will use unique technologies combining bio-inspired “hierarchical” ThermoElectric Energy Generating (TEG) carbon fiber (CF) reinforcements with novel thermoset matrix systems (3R Repair-Recycle-Reprocess technology). The aim of this combination is to evolve towards advanced TEG-enabled carbon fiber reinforced composites (CFRPs) for the Aeronautics sector. The hierarchical CF reinforcements will consist of fabrics of micron-scale CFs coated with efficient thermoelectric nanoparticles in a roll-to-roll coting process and impregnated in epoxy resins. This will consist in a “one run” process for prepregs (a composite with the described characteristics) manufacturing. For the first time, multifunctional TEG-enabled structural CFRPs will be developed that can store the TEG energy, acquire, and wirelessly transmit Structural Health Monitoring (SHM) signals for the composite real time in-service condition.
