Aplicación de materiales compuestos para la formación de guardabarros y tapas laterales de una moto de 125cc, 4 tiempos

Abstract

This thesis is based on the mechanical characterization of the composed polyester resin materials with a reinforcement of cabuya natural fibers, with configurations of long fiber normal tissue, ad volumetric fractions 25, 30, and 40 cc/cc; performing traction tests, fraction and impact according to American Society for Testing and Materials (ASTM) regulations for polymeric materials, determining the best alternative configuration for the fenders construction and motorcycle side covers 125 cc, 4 times urban type. After tests data was tabulated, it was obtained from materials resistance from laboratory in the universal machine Tinius Olsen for traction tests, for the impact tests of charpy pendulum, it was analyzed the mechanical properties determining the compound that has best features is was analyzed the mechanical properties determining the compound that has bet features is the configuration of long cabuya fiber (L.C.F) of 30 cc/cc fiber to the matrix with omax of 54.25 MPa and an E (Modulus of elasticity) 4157 MPa, obtaining a promising material to replace the fenders and side covers composed by steel or plastic which are distributed at market. Modeling elements and molds were made in Solidworks, in which a static analysis was performed with a load of 5000 N, this load represents a safety factor > 1 fitting with Fy from the test piece. From this study, it was proceed the creation of a cover side prototype through manual stratification as an element of mechanical best feature and manufacturing, showing the possibility to industrialize in lo scale these components as a contribution to technological disaggregation of the motorcycle whit, simple technology accessible in Ecuador
