In order to avoid accumulating large amounts of chicken feather waste, the study and the manufacturing of a new compost have been made. The said compost is formed by a matrix of EVA copolymer and the fibers are chicken feathers, so that they can be reused. To increase the interactions between the fiber and the matrix, the following has been studied: an EVA matrix modifier -a polymer that contains maleic anhydride (FUSABOND)-, and a compatibilizing agent (silane), which modifies the surface of the feathers. To prepare the compounds: the feathers have been cleaned, dried and grinded, the composite have been mixed with a Brabender, and compressed with a press of hot plates, and cooled down with water. The mechanical properties of the FUSABOND treatment at 180ºC with untreated and treated feathers are similar owing to the possible degradation of the silane at a high temperature. At 120ºC, the mechanical properties have increased owing to possible reactions between EVA, FUSABOND and silanes. The material obtained via the treatment of FUSABOND has a high yield strength, Young's modulus and tensile strength. However, the ultimate tensile strain has decreased. The mechanical properties without applying FUSABOND have not increased.
