Diseño y construcción de un chasis en fibra de carbono para un karting eléctrico bajo normativa internacional para la carrera de Ingeniería Automotriz

Abstract

This technical project developed the design and construction of a carbon fiber chassis according to international standards for an electric kart for the automotive engineering race. The project was carried out through the study of technical information on manufacturing processes dictated by the international control body of karting competitions (CIK-FIA), consequently it was required the analysis of the materials and implements to be used being these carbon fiber and epoxy resins, in addition to the implementation of additive manufacturing processes through 3D printers and destructive testing of composite materials used in the construction of the chassis, all this added to a virtual vision established by software simulations, which made observable the behavior of the chassis, which in terms of deflection with a value of 5.1715 mm, was the most worrying. As a result, deformation data were obtained that showed that the structure is not as rigid as expected, and that gave way to the study of specimens composed of TPU and carbon fiber as a measure of reinforcement for the structure. Considering the results, the use of carbon fiber as a coating for the joint-tube areas was ratified, which, when subjected to the simulation, reduced the deflection deformation to 2.7286 mm. It is concluded that the carbon fiber chassis was developed and can be implemented in the electric kart, based on the considerations presented in the project. A study of new materials for the fabrication of joints, epoxy resin and carbon fiber, as well as new methods to work the carbon fiber and present a single structure without the need of joining means is recommended.
