Composite Materials and Structures Group

Research within the group focuses on the modelling, development, manufacturing and machining of structures made of composite materials.

One of the strong characteristics of the group is to rely on fine experimental identifications of phenomenology be it for the problems of elaboration or damage. From the understanding of the scenarios, it is then possible to propose original modelling strategies (for example the development of specific finite elements for the calculation of structures or multiphysical routines for polymerisation). These models are usually filled in by a small number of objective experimental data. The approaches are then validated on structural problems, often close to industrial considerations. An example of this approach is the problem of frontal impacts on propeller blades. Developments carried out in the laboratory, via CIFRE theses are currently used by Airbus Helicopter for design and confidence in these methods means that they should be certified to do virtual frontal impact testing.

The group has therefore developed, over the years and projects, very strong skills and a culture in the development of original tests, understanding of phenomenology of composites, identification of parameters, modelling strategies and model validations. In general, the group positions itself more on the scale of the composite structure while having a fine knowledge of the material.

In the last five years, 60% of the research carried out was on subjects related to aeronautics, 50% in direct financing with an industrialist in this sector. The application themes are presented in the pages of the two axes SIMU and MaPP.

The MSC group is organized into two research axes:
MaPP « Proceeded-materials-Properties » axis
SIMU « Structure Impact Modelling Manufacturing » axis

 

Group organization:

Responsible: Bruno Castanié
Head of MaPP axis: Francis Collombet and Thierry Cutard
Head of SIMU axis: Xiaojing Gong and Samuel Rivallant
