Tecnología de manufactura de carrocerías de vehículos tipo GO-KARTS con el uso de material compuesto de matriz epoxi con fibra biodegradable yute

Abstract

The main objective of this research project is to characterize a new material by combining natural jute fiber with epoxy resin to new material by combining natural jute fiber with epoxy resin for the manufacture and fabrication of the fairing and manufacture of the components of the fairings that make up the bodywork of the competition go kart competition go kart vehicle. From the characterization and analysis of the tests, it was determined that the material biocomposite material of 70 porcentage epoxy matrix and reinforced with 30 porcentage jute fiber had the best tensile behavior under the standard (ASTM D3039- 2017) allowed us to carry out a procedure for the application of the material in the manufacture of the fairings of the go kart bodywork and by means of the impact simulation in the program Ansys Ls-Dyna reseach, the mechanical behavior of the models was evaluated in different phenomena, among them frontal impact, rear lateral impact and aerodynamic analysis of the maximum stresses that do not exceed 45.73 Mpa during the analysis time of 0.15 seconds. in the same way the aerodynamic behavior presented good characteristics in the flow of the aerodynamic behavior presented good characteristics in the air current flow, reaching a maximum fluid velocity of 12.07 m/s. Subsequently, the mold models were designed using CAD/CAE programs for manufacturing and engineering and parameters were established to build the molds. engineering and manufacturing software, and parameters were established to build the molds manually and with the manually and with the vacuum molding technique for each component that makes up the body of the go kart vehicle. the body of the go kart vehicle. Finally, a technological process is implemented for the manufacture of the body components such as the front, side and rear components such as the front, side and rear fairing and the steering cover with a thickness of 2mm. whose data show that the biocomposite has good resistance and mechanical behavior. good resistance and mechanical behavior.
