The use of thermoplastic olefins like polypropylene is currently growing in the automotive industry. However, the increase of wastes from end of life vehicles represents a threat to our environment. Mechanical recycling is the most acceptable and ecological method. The purpose of this thesis is to identify the thermomechanical degradation mechanisms of PP-based composites, as a function of fillers content. Recycling was simulated by multiple extrusions. The considered fillers consist of ethylene octene copolymer and talc. The different properties of recycled PP-based composites were studied by a multiphysical approach. A detailed study of high strain rate and temperature sensitivities of recycled PP-based composites is achieved. The micromechanical modeling is used to predict the yield and the elastic behaviors of non-recycled and recycled materials.
