The main aim of this Action is to enable the implementation of composite bonded joints in primary structures (critical-load-bearing structures). In order to achieve this, the Action will tackle the challenges related with the five stages of the life-cycle of a bonded structure:
1. ADHESIVE SYNTHESIZATION AND INTERFACE BONDING
Develop new eco-friendly adhesives and surface treatments that fulfil the REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) European regulations.
i) Develop fail-safe design for bonded structures in aircraft by making use of damage arresting capabilities; ii) Develop damage tolerance methodology for bonded structures; iii) Define analytical and/or numerical methods for typical application scenarios of bonded joints – including the set of material properties and related test standards required for the analysis.
i) Define the key manufacturing parameters for ensuring the production quality of the bond strength on a large scale; develop online monitoring methods for control and recording of the manufacturing parameters; ii) Assess the bond quality by non-destructive inspection; define suitable methods for different defect scenarios; iii) Develop upscaling scenarios for automated bonding and relevant design adaptations to enable an automated bonding process.
4. IN-SERVICE LIFE
i) Diagnosis and prognosis of the structural integrity of bonded structures under Environmental and Operational Conditions; ii) Define guidelines towards bonded repairs application.
Development of techniques that can efficiently disassemble bonded parts for repair and re-use purpose.
COST (European Cooperation in Science and Technology) is a funding agency for research and innovation networks. Our Actions help connect research initiatives across Europe and enable scientists to grow their ideas by sharing them with their peers. This boosts their research, career and innovation.
Bonded structures deal with very distinct fields, such as materials science, surface science, physics and structural mechanics. Nevertheless, in order to achieve industrial progress, an interdisciplinary approach has to be adopted in order to address the challenges of this topic. CertBond Cost action brings together experts in those different fields aiming to enable the implementation of composite bonded joints in primary structures.
