Can you tell us a few words about ArianeGroup?
Can you give us a brief overview of the Innovative Assemblies 2 project?
Why this collaboration?
In the case of bonded assemblies, it involves the preparation of surfaces to match the chemical composition of what is brought into contact with them, such as the adhesive. With IRT Saint Exupéry, we are working on surface preparation by laser and plasma in order to improve the reliability and costs of these assemblies. The aim of laser surface preparation work is to understand laser/material interactions and to search for the right parameters to achieve optimal surface conditions for bonding.
In plasma surface preparation, we activate the surfaces and seed the plasma with molecules that improve the reactivity of the surface for better bonding. These works have shown very interesting results and have been expanded now in production.
We are also working with the IRT Saint Exupéry on more original assembly methods, in particular to optimize bonds between composite and metallic materials or on metal additive manufacturing based technologies.
What were the strong points of this collaboration with the IRT Saint Exupéry?
The projects with IRT Saint Exupéry and the collaboration with the Academic Members (allowing to move from TRL 3 to 6) must provide an industrial response while relying on the best skills of the various project members in the target fields as well as the cross-disciplinary approach necessary for engineering problems.
