Popis: Composites with natural fibers are evaluated as a viable sustainability alternative to conventional materials, combining low-cost characteristics with consumer products. In Brazil, a considerable amount of lignocellulosic waste is discarded in nature, polluting the environment. Tucumã fruit (Astrocaryum aculeatum) generates about 60 tons/month of solid waste only in the city of Manaus (Amazonas State). In addition, the Amazon region has enormous deposits of clay silicate materials, such as kaolins, in the Rio Negro basin area that can be used as fillers in polymeric composite materials. This work investigates a new composite material (ETK) made of epoxy resin (ER), tucumã endocarp powder (TEP), and kaolin (K), without coupling agents, being a composite with a lower environmental impact design. The ETK samples were prepared by cold molding with 25 different compositions. Characterizations were performed by SEM and FTIR. Mechanical properties were determined through tensile, compressive, three point flexural, and impact tests. FTIR and SEM results showed an interaction between ER, TEP, and K. Incorporation of TEP and K reduced the mechanical properties of ETKs. Composites resulting from RE + TEP (10% to 40%) + kaolin (2% and 4%) have significant potential for use in industrial consumer products.
