MSC group

Composite Materials and Structures Group

The MSC group includes 30 permanent researchers (assistant, associate and full professors), close to 45 PhD students, 10 post-doc and project engineers. The group is organized in two research axes: Material Processes and Properties (MaPP) and Structures Impact Modelling Machining (SIMU)

The MSC group’s research focuses on the study of materials and composite structures at various stages of their life cycle:

• • Development, manufacturing and machining.
• • In service mechanical behavior.
• • Repair, reuse and recycling.

The proposed approaches combine experience, model development, and numerical simulation to achieve this.

The applications are mainly, but not exclusively, related to the aeronautical and aerospace sectors.

Group activities :

• • Composite life cycle: from the Manufacturing processes (development, machining, assembly, repair, recycling) to the structure.
• • Materials: fiber reinforced polymers (synthetic or bio composites such as: flax, jute, wood, cork, etc.), ceramic matrix composites, multi-materials.
• • Multi-scale approaches: from nano to macro scale (structure).

• • Multidisciplinary: materials science, solid mechanics, fluid mechanics, etc.
• • Multiphysics approaches: mechanical, physicochemical, thermal, electrical
• • Tests/Calculations: balanced approach between experimentation, modelling, and numerical simulation

Generic scientific methodologies across the group:

• • Experimental identifications of engineering phenomena applied to manufacturing problems, behavior, or damage.
• • Development of original tests for phenomenological understanding, parameter identification, model validation, and numerical simulations.
• • Development of strategies for specific modelling that are representative of the studied physics.
• • Development of multi-scale approaches to composite structures associated with material knowledge.
