Composites reinforced by lignocellulosic fibers and structural cellulosic materials, such as bamboo, have being increasingly used in many industrial fields, owing to the growing society need to use materials from renewable resources. Therefore, this study aims to analyze two agro-wastes of the cococnut and heart of palm sustainable production, which are the trunks of these palms (Bactris gasipaes and Cocos nucifera). The main objective is to establish the foundation for an alternative way of obtaining wood, considering the following aspects: availability, environmental conservation, good performance and low material cost. In this work microestrutural characterization of pupunha trunk was done by scanning electron microscopy and digital optical microscopy. The thermal and the thermo mechanical behaviors were evaluated by thermogravimetric analysis and by dynamic thermo mechanics analysis. Also rated was the material mechanical behavior in bending, compressing and shearing in the glue line. The material crystal structure and the degree of crystallinity was tested by X-ray diffraction. The resistance to abrasion was checked and the effect of aging due to water absorption and UV radiation in the bending properties of pupunha. Finally we verified the abrasion resistance and mechanical properties of bending and compressing the coconut palm.
