  • WP 1 - Management
    This WP aims to promote effective project management in respect to all activities carried out by the partners, as well as to facilitate the integration of talents and resources in order to reach the desired global outcome.
    The main objectives of the management activities are:
    • Coordination, monitoring and reporting of the project;
    • Administrative and financial management of the project;
    • Data management of the research input and output data;
    • Innovation management to maximize chances of data reusability and outputs exploitability.
  • WP 2 – Structural design, modeling, and simulation
    WP2 provides all the design and simulation activities of the project. WP2 will provide the objective OB1, which contribute achieving:
    • weight reduction compared to riveted joint;
    • tensile mechanical strength of 36MPa (+60% operational performance) provided by multi-material FEM structural model based on the metal-fiber-matrix RVE domain;
    • uniform stress distribution in metal part through topology optimization;
    • low mismatch between the thermal expansion coefficients of metal and composite through thermo-structural FEM model of the compensating lattice structures with RVE approach.
  • WP 3 – Fabrication of AM parts
    The WP3 will achieve the OB2 through the calibration and setup of LB-PBF process of AlSi10Mg alloy and the fabrication of AM metal parts for all the specimens and the prototype with the goals:
    • to optimize the LB-PBF process on AlSi10Mg for fabrication of hybrid structures with support of experimental validation of performances;
    • to build samples for fatigue and endurance tests and metal inserts for AM-CFRP joint samples.
  • WP 4 – Anti-corrosion and pro-wetting treatment of AM parts
    The WP4 provides the APPD coating process optimization and coating a¬pplication on metal samples and prototype fittings surfaces according to OB3 to (a) improve wetting to epoxy precursors as well as binding and adhesion to epoxy matrix and to (b) provide inhibitor based corrosion protection with "self-healing" capacity in case of damage. The coating is applied by aerosol-assisted APPD on complex surfaces with 3D anchoring features. Advanced CFD plasma simulations are used to optimize the gas flow in presence of geometrical undercuts. The same coating is then applied to the prototype metal parts and its KPIs are validated.
  • WP 5 – AM-CFRP joints fabrication
    WP5 will contribute to the OB4 by providing the fabrication of all the functional AM-CFRP specimen joints and the fabrication of the prototype. The sub-objectives are:
    • optimize the autoclave-cured prepreg process;
    • to build the AM-CFRP samples by joining AM coated metal inserts with CFRP;
    • to build the prototype (vertical stabilizer) by autoclave-curing with previously build metal coated inserts.
  • WP 6 – Certification methods and tests for materials/products/processes
    WP6 will provide the OB5. The technical requirements from the normative and the best-practice guidelines will be defined by 7-TUV to align the project (i.e. activities, technologies, facilities, materials, and treatments) to prescriptions. The actions to achieve the technical requirements and to establish the safety levels are actuated and the guidelines for pre-standardization and further certification of materials, processes and components are provided. The sub-objectives are:
    • to define normative requirements related to the project, in particular the design requirements, the implementation and management of the fabrication process, and the testing setup for material, structures, and components;
    • to define the actions needed to get multi-disciplinary optimization of the production process and components properties/performances in relation to normative prescriptions.
  • WP7 – Joints disassembling and metal recycling by powder regeneration
    In WP7 the disassembly of the multi-material joints and the recycling of the AlSi10Mg metal part are performed. This WP contributes to achieve the OB6, in particular regarding the separation of joints materials and the recycling of AlSi10Mg parts as powder with verified quality standard by providing added value for circular economy.
  • WP 8 – Operative tests on materials and components
    WP8 contributes to achieve the OB6, regarding the completion of the recycling process of CFRP materials. 6-GBP will transform the composite flakes produced in WP5 to obtain granular fillers for advanced polymers industry. Target particles recycling efficiency = 90% of initial weight of composite material.
  • WP 9 – Dissemination & exploitation
    WP9 will contribute to achieve the OB7 by means of test campaigns for characterization and validation of materials and processes. Static characterization of CFRP samples is used to optimize the plies composition and autoclave-curing setup (ASTM D3039). AM-CFRP are validated to identify the optimal 3D anchor shape and relative mechanical strength (ISO 22841, ASTM D3528). Fatigue tests are provided on CFRP and AM-CFRP joints (ASTM D3479, ISO 9664). 1-POL provides the test facilities, 7-TUV and 8-BYT provide the test facilities and tests setup according to aeronautic certification requirements, 3-LEO provides the applicative context for the normative. The prototype structure (joined component of vertical stabilizer) is validated by experiments, in relation to aeronautic normative.
  • WP 10 - Dissemination/exploitation
    The main objectives of this WP are:
    • to effectively disseminate the results of the project making them available and fully accessible,
    • to develop an effective communication campaign outside the consortium,
    • to develop a business plan and follow up strategy for the Project exploitation, and to validate this plan by means of the prototype by achieving the OB8 to engage stakeholders in the development of the project.
