Diseño y construcción de un molde para asientos de karting a medida de fibra de carbono

Abstract

This graduation project deals with creating a mold for karting seats, with an emphasis on using carbon fiber with epoxy resin to achieve an ergonomic and safe design. The importance of the seat in the pilot's performance and safety was recognized, as it provides the foundation for efficient and comfortable driving. It was highlighted that, although the engine and mechanical preparation often receive more attention, seemingly secondary components like the seat play a crucial role in the overall performance of the kart. Karting, as a high-risk sport, requires special attention to ergonomic and safety details. The relevance of weight, comfort, and aerodynamics in vehicle performance, as well as in the comfort and concentration of the pilot during competition, was underscored. The study mentioned that a low-quality seat can negatively affect pilot performance and even pose a safety risk if it breaks during the race. Exhaustive traction and flexion tests were conducted to evaluate the strength of the composite material, providing essential data that supported simulations carried out in CAD software. Additionally, a thorough demolding analysis, crucial for mold fabrication, was performed. We opted for the lamination method, initially constructing a foam seat prototype before progressing to the creation of the final mold in carbon fiber. The tests and simulation provided the necessary confidence to ensure the functionality and effectiveness of the mold in practical application. As a result, we successfully constructed the carbon fiber mold, along with results validating its construction, such as minimal deformations in the Y and X axes, as well as an appropriate safety factor for manufacturing on the built mold.
