This project aims at establishing post-processing methods for a better understanding of the mechanical and anisotropic fracture behavior of nacre-like ceramic composites. These methods will couple two full-field measurement approaches, namely Raman spectroscopy for local stress field measurement and digital image correlation (DIC) for local strain field measurement. This coupling will be set-up during in situ mechanical testing.

As the world fights to tackle climate change, securing affordable, net-zero energy stands out as a paramount engineering task for ensuring a future for our and next generations. Among the pivotal technologies necessary to direct energy systems toward sustainability and net-zero emissions is Carbon Capture and Storage (CCS). CCS comprises several technologies which involve capturing CO2 from major point sources, followed by compression and transportation to appropriate underground reservoirs for either sequestration or enhanced oil recovery.

L’objectif est de développer une solution française de fabrication d’outils en carbure de tungstène par fabrication additive (Binder Jetting) servant des industries de pointe telles que l’aéronautique, l’automobile, l’énergie, le naval ou encore l’armement. La chaine de valeur sera abordée dans son ensemble : de la poudre à la pièce. Des retombées sociétales fortes sont attendues avec le développement des compétences et des emplois, et l’économie d’énergie et des ressources de matériaux rares.

Ce projet a été financé par l’État dans le cadre de France 2030.

Aluminum alloys are used extensively in aircraft due to their high strength-to-weight ratio. A main drawback is that their microstructure is sensitive to corrosion, which generates pits for example. Although corrosion damage can be detected by non-destructive testing methods, such methods are limited in their ability to identify corrosion initiation and the mechanism behind the defect. As a result, corrective actions are only undertaken when corrosion becomes evident (cracks or loss of thickness).

Since the emergence of nanotechnology in the 80s, block copolymers are frequently used to design "preforms" to control the structure of inorganic nanoparticles. MANIOC's philosophy is based on the opposite reasoning. It consists in manipulating the microstructure of triblock copolymers by selectively adsorbing their ends on the surface of “stimulable” and “guidable” magnetic particles. The experimental process, allowing the design of non-equilibrium microstructures on demand, can be summarized in three steps:

The introduction of fuel cells for surface vehicles requires a review of stack concepts to make them lighter, more compact and more durable. These objectives require, among other things, the development of new materials dedicated to the bipolar plate. The MATEIS (Materials: Engineering and Science) laboratory has been asked to work on the conceptualisation and performance evaluation of these new materials. To do this, it is using its expertise in surface engineering, corrosion science and electrochemical measurement.
