Análisis del proceso de obtención de un material compuesto de matriz epoxi reforzado con fibra natural y sintética mediante transferencia de resina por infusión al vacío (VARTM)

Abstract

The generation of new composite materials that present good mechanical characteristics, for different user needs, is important to improve the production characteristics of local and even national businesses. It should also be taken into account that many times, this change must necessarily be friendly to the environment and generate the greatest amount of product, taking advantage of the minimum necessary resources; this maximizes productions and profits. This paper presents the characterization of the process that must be carried out to generate composite material laminates, with different parameterizations, made based on an epoxy resin matrix, reinforced with natural Chambira fibers, in different directions, and synthetic fiber, purely flat fiberglass fabric, through the Vacuum Infusion process, carried out with a vacuum pump. Bearing in mind that there may be variations in the forming process of said material, as well as in certain punctualities of the conforming elements. Subsequently, the acquired properties of each of the cases were verified, through an analysis of the production times, the weights before and after the forming process and a tensile test, made under the parameters of the ASTM D3039 standard, which provides us with the characteristics that must be analyzed of each tested specimen, this in order to verify the acquired qualities, as well as a possible comparison of the uses that the material may have.
