Composites with natural lignocellulosic fillers are being cited as a viable and sustainable alternative to conventional materials, they combine lower costs weight. In many tropical countries, such Brazil, there is considerable amount of waste that improperly discarded, which causes pollution the environment. The Amazon region has huge deposits clay silicate materials in Negro River basin, kaolin, can be used polymeric composite materials. This work investigates new material (ETK) made epoxy resin (ER), powdered tucumã endocarp (PTE), kaolin (K), without coupling agents, aim producing environmental impact. ETK samples, totaling 25 different compositions, were prepared by cold molding. Characterizations samples performed using scanning electron microscope (SEM) Fourier-transform infrared spectrometer (FTIR). addition, mechanical properties determined via tensile, compressive, three-point flexural impact tests. FTIR SEM results showed an interaction between ER, PTE, K, incorporation PTE K reduced samples. Nonetheless, these composites considered potential for engineering applications high strength not main requirement material.
