HARVEST is a 36 month project that will cover the whole value chain of Fiber Reinforced Plastics (FRPs) so as to provide novel FRPs capable of harvesting and storing thermoelectric energy. In addition, HARVEST will develop a purposefully made electronic circuit module so as to power SHM inherent functionalities and provide information on the structural health of the components.

To this end, HARVEST is composed of an interdisciplinary consortium of academics, key technology providers, industrial/SME partners and standardization experts to ensure the applicability of the developed materials in future aerospace applications.

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.

2018 - ThermoformAble, repairable and bondable smart ePOXY based composites for aero structures

airpoxy logoComposite & Smart Materials Laboratory (CSML) is delighted to announce that it will be participating in the AIRPOXY project from September 2018. AIRPOXY is a 42-month collaborative project funded by the European Commission in the HORIZON 2020 framework with a total budget of €6.5m. The aim of this project is to reduce production & MRO (maintenance, repair and overhaul operations) costs of composite parts in aeronautics. This will be achieved by introducing a novel and new family of enhanced composites that preserve all the advantages of conventional thermosets, while showing Re-processability, Reparability and Recyclability (3R). AIRPOXY will develop new thermoset resins from TRL3 (Technology Readiness Level) to TRL5 through two representative demonstrators of aircraft panels.
CSML will implement structural health monitoring (SHM) technologies in order to detect in service damage and analyze the damage tolerance of the new composites. CSML will test various specimens geometries for different levels of damage (matrix cracking, delaminations, etc.) and then, develop and optimize the SHM technologies using a variety of Non-Destructive (NDE) techniques. In the demonstrator level, CSML will integrate the developed SHM technologies for validation and further optimization.
The AIRPOXY project is led by CIDETEC and it is formed by a multidisciplinary consortium of 11 partners from 6 countries; CIDETEC (Spain) as resin inventor, key technology providers IVW (Germany) (thermoforming & welding), Eurecat (Spain) (RTM), Coexpair (Belgium) (SQRTM), University of Ioannina/Composite & Smart Materials Lab (Greece) (Structural Health Monitoring); Altair (France) (process simulation software), aircraft components manufacturers (EIRE, Ireland); IDEC, Spain); SONACA, Belgium), standardization experts UNE (Spain) and an aeroconsultancy (ARTTIC, France).

 • HIPOCRATES is a Collaborative Project co-funded by the 7th Framework Programme of the European Community. Further information on European Community research programmes can be found on the Cordis web site.

• The aim of HIPOCRATES project is to serve as a platform for developing the required knowledge, technologies, procedures and strategies to deliver self-repairing composite aero-structures, while defining the roadmap to achieve the vision of self-repairing composite structures.

In order to achieve this aim, the objectives of HIPOCRATES research and development activities are set to give answers in certain directions:

• To provide experimental evidence to meet the State-of–the-Art shortcomings and broaden the understanding of the self-healing mechanisms.

• To develop strategies and respective procedures for enabling self-repairing of composite materials by critically analyzing the established techniques.

• To establish novel routes and technologies for utilizing the self-healing functionalities in aero-structures.

• To develop new protocols and testing methods in order to specifically quantify the healing magnitude.


Bonded composite patches are ideal for aircraft structural repair as they offer enhanced specific properties, case-tailored performance and excellent corrosion resistance. Bonding further eliminates stress concentrations induced from mechanical fastening of metal sheets, seals the interface, and reduces the risk of fretting fatigue between the patch and the component.

IAPETUS focuses on the use of improved composite repair systems offering (i) the introduction of new on-aircraft simplified curing technologies, (ii) enhanced fatigue and damage tolerance properties and (iii) integrated damage sensing. This will be performed via the incorporation of carbon nanotubes (CNTs) both in the composite matrix of the repair patch as well as in the adhesive. The use CNT modified repair concept will lead to improved performance in the blunting of stress concentrations in the parent surface and the inhibition of crack propagation, leading to enhanced fatigue resistance at the locus of the repair as well as for the patch itself.

At the same time, the patch repair acquires additional functionalities. The CNT doped Carbon Composites can be tailored to reduce the galvanic corrosion in repaired Aluminium structures. As the patch becomes electrically and thermally conductive thermal energy can be infused in the patch either by direct resistance heating (using the patch itself as heating element via the application of electrical voltage) or by induction heating, to instigate a uniform matrix polymerization since the patch system appears improved thermal conductivity too. The electrically conductive percolated network can be employed to assess the damage within the patch and its interface with the repaired structure, as conductivity changes mirror the damage in the doubler/substrate system by tracing micro damage through breaches in the CNT network; thus, the structural efficiency monitoring at any stage in the service life of the aerostructure can be assessed non-destructively.

IAPETUS is realised by 7 industrial partners (Fundación INASMET Spain, PZL-Swidnik Poland, Huntsman Advanced Materials GmbH Switzerland, Integrated Aerospace Sciences Corporation (INASCO) Greece, DAHER Aerospace France, GMI AERO France, Hellenic Aerospace Industry SA Greece) and 3 Universities (University of Ioannina Greece, University of Sheffield UK, University of Patras Greece).



Multifunctional Composite Materials

Special Issue Information

Dear Colleagues,
Composite materials have been studied for several decades already. Particularly in the last decade, the use of structural composites materials has literally been booming in the aeronautics and automotive industry. This is marking a notable change in design mentality, i.e., the tailoring or “architecturing” of material in accordance with structural needs, a possibility uniquely offered by advanced composites. It is this mentality that gave birth to the next generation of composites, that of multifunctional composite materials. These materials made “by design” possess the required improved specific properties but are also equipped with additional properties which impart to them other functionalities, which may be structural or nonstructural.
To this aim, the hybridization of otherwise “traditional” composites has been widely studied. A typical case study is that of embedding nano-scaled reinforcement into the matrix of usually micro-scale reinforced systems, with a view to both enhancing the matrix dominated properties as well as imparting multifunctionality. In the literature, the additional functionalities provide diverse nonstructural capabilities, such as inherent structural health monitoring, sensing and actuation, power harvesting, and power storage, in addition to structural ones such as wear resistance, morphing or self-healing. The parallel structural and nonstructural capabilities of the new generation composites aim to enhance product life and increase product utility with minimum structural aggravation.
Functionalities imparted to the materials may be passive, active or even adaptive. For example, a material is subjected to a certain field during its service life. Thus, the material has to first sense the field effect, and, if it possesses some degree of “awareness”, evaluate it and even respond so as to adapt in order to retain its performance requirements. To perform these functionalities, there are power and coupling requirements. Additional to these requirements, the reliability and durability of such systems is also a major issue, as the functional properties need to extend throughout the service life of the material. Finally, one the major challenges related to multifunctionality is the provision of engineering to integrate these functionalities in the composite structure at a system level, whereby the architectured composite system will be enabled to perform the full cycle, i.e., sense–evaluate–react, in response to the external stimuli, be they mechanical, environmental or other.
This is an outline of the issues that form the scope of this Special Issue. Research papers are invited in relation to multifunctional advanced composite materials, smart materials, sensing and self-diagnosis, actuation and morphing, inherent energy harvesting and storage capabilities, environmental property enhancement, electromagnetic shielding, and in any other field where the materials by design perform in diverse ways so as to respond successfully to their service conditions.
