Recently, the growing concern about the environmental impact caused by modern society has led the scientific community to seek new technologies and sources of sustainable resources. In this perspective, natural lignocellulosic fibers are studied for use as engineering materials. Thus, the present work has the objective of creating composites of epoxy matrix of high mechanical performance reinforced with curaua natural fibers. The curauá fiber has reported resistance in the literature up to 3000 MPa. However, the difficulty of creating a good interface between matrix and reinforcement makes the higher results of polymer matrix composites present a loss of mechanical performance when compared with the expected theoretical value and have a high statistic dispersion. In this work, tensile strength results demonstrate that the presetting of the processing parameters can raise the mechanical strength of the material up to 335 MPa with a dispersion of about 6%.
