The search for more sustainable lifestyles has become more urgent over the years. In a context of increasingly drastic climate change and global scale measures in order to slow down the harm of human activity to the environment, the choice for sustainable materials from renewable sources is revealed as one of the most promising solutions to this problem. The present work is dedicated to the study of the reinforcement of composites from natural fibers obtained from coconut, sugar cane bagasse and wood and the characterization of the mechanical properties to the creep of these composites, in order to analyze the viability of the use of these materials as new alternatives to what is usually found in the industries. From the determination of the creep behavior of these composites, interesting applications can be identified in constructions, for example , so that both the economy and the environment benefit from more sustainable options. Through this study, the deformation curves of the mentioned composites were traced and, thus, an estimate of their service life was made
