Diseño y construcción de un protector frontal para karting fabricado de un material compuesto de abacá poliéster

Abstract

The consistency of the materials is a key factor to consider for the construction of automotive parts. This work is oriented to look for solutions with alternative polymeric materials that can substitute the materials used such as fiberglass. A polymeric material composed of a polyester matrix with abaca fiber reinforcement is corroborated, which presents a good energy absorption. It is conformed with a 30% volume fraction of fiber and a 70% of matrix with the configuration of woven fabric reinforcement. The specimens were elaborated according to NTE INEN 2043 type D1 standards for tensile tests, while NTE INEN 2047 standard were used for flexural tests; acrylic molds were built to generate the type of specimen suitable for the studies. The type of stratification used is mold casting. To carry out the studies, the machines and laboratories at Universidad Técnica de Ambato were used, as well as Centro de Fomento Productivo Metalmecánico Carrocero in Tungurahua province. Two tests were carried out to obtain the characterization of the material and to elaborate the material behavior curves. For the simulation of the static analysis of the front protector of karting, the ANSYS software was used, with the values obtained from the study of the polymeric composite material with the woven abaca fiber, where when applying the same force in three directions (front, top and side), it was evidenced that when obtaining a lateral force is where more deformation will be in the front protector of the karting in comparison with forces in front and top direction.
