Positioning – Mechanics of Composite Materials and Environment Department
This department is developing its activities on two themes: innovative materials and composite structures and analysis and reduction of polluting emissions with a focus on the environmental factor
1. Innovative Materials and Composite Structures activity
This activity is organised into two topics:
- Eco-composites in structural design
- smart materials and structures
a) Eco-composites in structural design
This theme covers the whole life-cycle of the material: from manufacturing the fibre to recycling the structure.
Its objectives are:
- Promote the use of eco-composites of low environmental footprint in the transport domain (particularly structural parts);
- Control the influence of the manufacturing process on the physicochemical properties (micro-structural) and on mechanical characteristics;
- Experimenting, developing numerical simulation and improving materials behaviour in quasi-static, under impact, at dynamic tests under a controlled environment.
b) Functional materials
The requirements of this topic are:
- Study and design composite materials including specific functions such as acoustic and vibration absorption or damping and electrical conductivity or resistance;
- Study the impact on the mechanical strength and manufacturing processes when these specific functions are introduced;
- Study the problems related to composite/composite and composite/metallic interfaces, particularly from a thermal and manufacturing-process point of view.

2. Analysis and Reduction of Polluting Emissions activity
- This theme focuses on:
- The physics of aerosols;
- The study of particulate deposit processes that come into play in the de-pollution of gas/particle mixtures;
- The study on coupling between flow turbulent structures and the spatial-temporal movements of particulate pollutants.
