Item Análisis de la incidencia de retardantes de llama (hidróxido de aluminio, hidróxido de magnesio) en las propiedades mecánicas de un material compuesto de matriz polimérica reforzado con fibra de vidrio utilizado en la fabricación del interior de carrocerías metalmecánicas(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2019) Freire Bonilla, Oscar Fabricio; Castro Miniguano, Christian ByronThe present experimental work was carried out in order to demonstrate the influence of flame retardants on composite materials (glass fiber + polyester resin and glass fiber + epoxy resin), in order to determine the impact on the mechanical properties of the same, looking for new fire resistant materials that have properties similar to the original composite materials. In this research 12 groups of composite materials were made, of which the results of their mechanical properties will be exposed, the specimens were manufactured according to the standards (ASTM D-3039) for traction, (ASTM D-7264) for bending and the standard (ASTM D-6110) for impact. For the analysis of results the 12 groups were compared with 2 extra groups, the latter being the original composite materials (fiberglass + polyester resin and glass fiber + epoxy resin), the respective correlations were made in which correlations were evidenced in mostly positive. The combinations of the 12 groups and the 2 extra groups, when an ANOVA analysis was carried out with the help of a software, it was determined that there is an incidence in the mechanical properties when the flame retardants are added in the original composite materials
