Development of Bio-composites Based of Polymer Matrix and Keratin Fibers: Contribution to Poultry Biomass Recycling

摘要

Processing of the poultry feather biomass into useful products presents interesting opportunities of recycling agricultural waste material. According to a chemical process developed in our laboratory, poultry feathers were converted into wool, fibers or powder so as to meet several applications in many fields. Due to of their unique structure and to their physical properties, a suitable molding technique was performed in order to produce composite samples highly filled. The concentration range was varied from 10 to 50% by weight with an increase of 10, because of practical reasons. The morphological, thermophysical and mechanical investigations of polyester matrix filled with several concentrations of the keratin fibers show interesting results.
