Mechanical characterization of jute fiber-based biocomposite to manufacture automotive components Jorge Antonio Velasco Parra, Bladimir A Ramón Valencia, and William Javier Mora Espinosa Universidad Nacional Autonoma de Mexico In this research work, samples of the biocomposite were manufactured using the vacuum assisted resin transfer molding (VARTM) technique, whose matrix is a polyester resin and the reinforcement is a biaxial fabric (90°) made with jute fiber. Then, tensile and flexural tests were carried out on standardized specimens under ASTM standards, in order to mechanically characterize the jute-polyester biocomposite. In both destructive tests, the results showed a linear-elastic behavior with brittle fracture and greater strength of the jute-polyester biocomposite, with respect to the thermosetting matrix’s properties. Subsequently, a finite element based static analysis was performed, with the help of the ANSYS software, to determine the mechanical behavior of interior opening handle for a car door. In it, a model sensitivity study was run to determine the influence of the mesh type and identify the convergence of mesh. Later, the static analysis results were obtained: critical zone, maximum operating stress and safety factors. The results obtained computationally validate the use of jute-polyester biocomposite, as a substitute for the manufacture of an interior opening handle for a car door. Finally, a scale model of the piece made with jute-polyester biocomposite was manufactured.
