The objective of this paper was to study the mechanical behavior, degradability and its physical properties of six starch – based biocomposites reinforced with bagasse fiber, made with three different fiber lengths (1 mm, 0.5 mm and 0.25 mm) and with or without the application of an alkali fiber pretreatment. Biocomposites were characterized by mechanical tests (tensile, compressive and flexural), as well as water absorption and biodegradability analysis. The mechanical strength of the material was significantly influenced by the alkali fiber pretreatment and fiber length. The weight loss of all composites, attributed to their biodegradability, was higher than 70 % after the fourth week. The mechanical strength of the composite with fiber length of 0.25 mm and alkali fiber pretreatment was higher than the other treatments, thus, the mentioned composite is a promising eco-friendly proposal for many applications. El uso de materiales biocompuestos de matrices poliméricas biodegradables reforzadas con fibras naturales es una propuesta ecológica para diversos sectores de aplicación. El objetivo de esta investigación fue elaborar y estudiar el comportamiento mecánico, la degradabilidad y las propiedades físicas de seis biocompuestos hechos a base de almidón de arroz y fibra de bagazo de caña con tres longitudes (1, 0.5 y 0.25 mm) y con o sin la aplicación de un tratamiento alcalino. Los biocompuestos se caracterizaron mediante pruebas mecánicas de tracción, flexión y compresión, así como de absorción de agua y biodegradabilidad en suelo. La resistencia mecánica del material, se vio altamente influenciada por el tratamiento alcalino de la fibra y la longitud de la misma. La pérdida de peso de los seis biocompuestos, atribuida a su biodegradabilidad, fue superior al 70 % después de cuatro semanas. El biocompuesto con longitud de fibra de 0.25 mm y con tratamiento alcalino resultó ser el más resistente en todas las pruebas mecánicas de todos los tratamientos analizados y representa una propuesta ecológica prometedora para diversas aplicaciones.

The use of composite materials of bio-based polymers reinforced with natural fibers has been an eco-friendly alternative to several application sectors. The objective of this paper was to study the mechanical behavior, degradability and its physical properties of six starch – based biocomposites reinforced with bagasse fiber, made with three different fiber lengths (1 mm, 0.5 mm and 0.25 mm) and with or without the application of an alkali fiber pretreatment. Biocomposites were characterized by mechanical tests (tensile, compressive and flexural), as well as water absorption and biodegradability analysis. The mechanical strength of the material was significantly influenced by the alkali fiber pretreatment and fiber length. The weight loss of all composites, attributed to their biodegradability, was higher than 70 % after the fourth week. The mechanical strength of the composite with fiber length of 0.25 mm and alkali fiber pretreatment was higher than the other treatments, thus, the mentioned composite is a promising eco-friendly proposal for many applications. |
