Caracterización de la interfaz de un material compuesto de matriz polimérica reforzado con fibra natural obtenido por medio de dos procesos diferentes con el uso de microscopía : caracterización de la interfaz de un material compuesto de matriz polimérica reforzado con fibra natural obtenido por medio de infusión al vacío con el uso de microscopía.

Abstract

This work details the obtaining of a composite material with a polymeric matrix based on polyester resin, reinforced with natural cabuya fiber fabric, through the vacuum infusion procedure through which laminates are manufactured from which different types of test tubes are obtained. To be characterized to determine the physical and mechanical properties of the material. The tests carried out are those of traction according to the parameters established in the ASTM D3039/D3039 M-17 standard, bending according to the ASTM D7264/D7264 M-15 standard, and impact that complies with the ASTM D7264-96 standard. Subsequently, a microscopic analysis is carried out in the failure zone of the tested specimens to determine the state of the matrix-reinforcement interface in the material. Finally, a comparison of the results is made against other curricular integration work carried out under the same elaboration parameters for the material (relative amounts of matrix, reinforcement, and additives) but under a different process for obtaining the laminate, in order to determine Which method gives the best results? It was possible to conclude that the best results in terms of physical characteristics and mechanical properties are obtained with the vacuum infusion process used in this work.
