Abstract :

Today, composite materials are increasingly used to replace metallic structures, which allows a significant gain in mass. In addition, they are finding significant application in the aeronautics and automotive industries.
However, a thorough analysis of their behavior is necessary to ensure their life cycle.
On one hand, the numerous applications in the fields of transport and energy in particular call for hybrid multi-material structures that are subject to complex stresses.
On the other hand, many industries are sources of rubber and polymers pollution. Therefore, researchers aim to develop innovative processing techniques, which could reuse the residues of these materials by reducing the amount of waste generated.
My research project focuses on the study of functionalized composites based on recycled rubber and polymer materials under coupled multi-physical stresses. It is articulated around the strategy of regeneration of composites. It is a polymer/elastomer/metal matrix from industrial production residues, doped with a functional reinforcement.
The objective of my thesis is to highlight the linkage between the choice of the recycling method, the choice of the manufacturing process and the behavior on the mechanics of damage, rupture and durability.
The aimed results for the end of my thesis are first a developed and validated experimental protocol for the production of new composite materials. Then, a well-controlled manufacturing process followed by the realization of precise characterizations. Then, a multi-physics modeling of the material behavior under stress. And finally, an analytical identification taking into account all the parameters of the process with the implementation of a data management plan.
