Aprovechamiento del residuo agroindustrial (Expeller de Linaza) para obtener productos biodegradables con el 20% de fibra Trabajo de integración curricular previo a la obtención del título

Abstract

Abstract: This paper addresses the use of flaxseed expeller agroindustrial waste as a raw material for the production of composite materials with 80% HDPE and 20% flaxseed fiber, with the aim of combating environmental pollution caused by plastic and agroindustrial waste. The fiber was chemically treated to improve the compatibility between the polymer matrix and the fiber. It was evaluated through mechanical compression, tensile, and flexural testing. The results showed that the chemical treatment reduced the elastic modulus by 13.21%, but increased the maximum stress by 7.42% and the strain by 17.93%. In compression, the elastic modulus increased by 14.7% and the maximum stress by 6.9%, indicating greater stiffness and strength. In tensile testing, an increase of 48.87% in the elastic modulus and 46.6% in the maximum stress were recorded, reflecting a significant improvement in mechanical strength. The results demonstrate good adhesion of the flaxseed fiber to the polymer matrix, which improved the mechanical properties of the composite material.
