Recycling effects on the dynamic response of composite based polypropylene is studied in this paper. Materials used here are filled and unfilled impact modified polypropylene. Nodules of EPDM represent the elastomeric phase for the filled composite based polypropylene. Fillers are particles of talc. For the unfilled polypropylene, the elastomeric phase is nodules of EPR. Different tensile tests, until rupture, were performed from quasi static to high strain rates. Virgin specimens were recycled in order to study the degradation due to the effect of recycling under dynamic loading. Thus microstructural effects due to dynamic loading and recycling were observed by SEM.
