Abstract
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.
