Analysis of the Physical and Chemical Properties of Biocomposite Materials Obtained from Feather Flour and Polypropylene

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, in order to obtain granules. The granules were injected in various forms to evaluate the properties. The composite materials have been evaluated for 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 physico mechanical properties were analyzed in order to identify a composite with optimal properties for industrial application.

Acoustic Properties of a New Composite Material Obtained from Feather Flour and Recycled Polypropylene

“…Recycled polypropylene was mixed with feather flour in the proportion between 10 and 50 %. A comprehensive description of preparation method was described in previous works [9]. In order to improve adhesion between composite components, additives were added (32%).…”

“…The obtained granules, using various recipes described in previous work [9], were placed inside the mold until it was filled enough to allow the placement of the lid provided with a uniformity disk. Then, the mold was heated in the oven to 200ºC for up to at 5 min, depending on each recipe composition (the amount of added feather flour influences the viscosity of the mixture).…”
