The current technological growth has pushed the manufacturing sector to undergo important changes during the latest fashion in the field of advanced manufacturing, manufacturing articles in full technological development under a 4.0 environment, manufacturing is no longer just about manufacturing physical products. Here in this article, we seek to develop a reinforced biobased composite material based on polypropylene with natural fibers in order to improve its mechanical properties, for its application in the automotive and aeronautical sectors or others in general. Highlighting the objective, interest, argument of the study and importance of the problem, a chemical characterization methodology was used in the natural fibers of banana pseudostem to obtain the best possible results from this study and to be able to adhere to a polymeric matrix, thus obtaining a composite material. already prepared, for a study in the second methodology now is a physical characterization and to be able to submit it to a scanning electron microscopy (SEM). And to other universal tension and compression equipment, to know their morphology and characterization of the fiber and polymeric matrix. This concept of the circular economy has recently been questioned by studies that show that the innovation of new composite materials provides remanufacturing, recycling, non-extraction of non-renewable materials and the use of clean energy, this is a contribution to the sustainable development objectives of the 2030 agenda. And it is a very involved topic with today's industrial engineering, since it has a very advanced profile for materials, manufacturing, and sustainability.
