Caracterización de un material compuesto empleando un tratamiento químico en el 20 % en peso de fibra de cebada

Abstract

Abstract: In this research project, a composite material composed of 20% barley fiber and recycled high-density polyethylene (HDPE) was created with a chemical treatment of the barley fiber. The chemical treatment consisted of applying 3% stearic acid in a methanol solution to the barley fiber to improve the compatibility between the fiber and the plastic. Once the material was formed, it was evaluated using mechanical tests: tensile, flexural, and compressive. These tests yielded data on the modulus of elasticity, maximum stress, and maximum strain. The results showed a 28.59% decrease in the tensile modulus, a 23.19% increase in the flexural modulus, and a 33.11% increase in the compressive modulus, compared to the material without chemical treatment. These values ​​highlight a possible improvement in polymer-fiber interaction.
