Abstract: 
The study is highlighting the possibility of modeling the properties of composite materials based on recycled polypropylene (PPR), flour feathers (FF), and compatibilizers (C). The composite materials with 10% and 20% feather flour content were mixed and processed with a two-stage extruder having four heating zones between 200-230°C, to obtain granules. The granules were injected in various forms to evaluate the properties. The composite materials have been evaluated for the determination of melt flow index (1900C; 2.16kg), density, Charpy impact, breaking strength, elongation at break, and the dielectric behavior. The results showed that the introduction of feather flour in the polymer matrix based on PPR leads to decreased flow properties as well as physical and mechanical properties. The solution in solving these deficiencies was to use compatibility agents, that would improve these properties. The physicomechanical properties were analyzed to identify a composite with optimal properties for industrial application.
