This study deals with the preparation and characterization of thermoplastic composites using polypropylene, high-density polyethylene and polylactic acid matrices and including whole chicken feathers as reinforcement. The behaviour of the composites was determined in terms of physical and mechanical properties, which were related to the fibre–matrix compatibility analysed by Fourier transform infrared spectroscopy and scanning electron microscopy. The results showed that the addition of chicken feathers into the thermoplastic matrices results in a slight increase in the stiffness when small amounts of chicken feathers (5–10% vol/vol) were incorporated into the composites. Tensile strength at maximum load, elongation at break and toughness properties decreased when the chicken feather concentration was increased. Results for chicken feather–polypropylene composites were analogous to chicken feather–high-density polyethylene and chicken feather–polylactic acid composites. The Fourier transform infrared spectroscopic study and the scanning electron micrographs suggest that the insufficient compatibility of chicken feather and polymer matrices is the main reason for the decrease in tensile properties

Mass production of tires, as well as the difficult storage or elimination is a real environmental problem. Various methods for recycling tires are currently used, such as mechanical grinding, which puts vulcanized rubber, steel, and fibers apart. The rubber may be used in several industrial applications such as flooring, insulations, footwear, etc. The aim of this article focuses on finding a new application for the old used tires (GTR). Tire dust and recycled EVA thermoplastic have been mixed, and we have checked the maximum accepted values of GTR concentration that can be admitted while keeping dielectric, mechanical, and thermal properties within acceptable values, as well as initial polymer microstructure. This would allow including GTR in industrial applications of recycled EVA. The recycled tire dust which result from the industrial milling processes has been divided by sieve in three different categories according to the size of the particles (<200, 200—500, and >" xbd="654" xhg="622" ybd="1596" yhg="1560"/>500 µm). This has then been mixed with EVA in different GTR concentrations (0%, 5%, 10%, 20%, 40%, and 70%) in order to establish its conduct through electrical, mechanical, thermal, and microstructure tests, which will be held in a range of temperatures between 30°C and 120°C, and with a range of frequency between 1 × 10-2 and 3 × 106 Hz.
