सारांश: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.
