Caracterización mecánica del material compuesto de matriz elastomérica reforzado con fibra de cabuya para determinar las propiedades mecánicas en aplicaciones industriales

Abstract

The study was conducted out in order to generate technological and scientific benefits to the conformation of new composite materials that have been considered high growth and demand in the global market, considering lighter materials and low manufacturing cost that have equal or superior mechanical and physical properties that will replace the materials that have traditionally been presented in the industry. The experimental work was perform the mechanical characterization of latex matrix composite material reinforced cabuya short fiber with random with random orientation and volumetric fractions of 20% latex-80% fiber of cabuya, 30% latex-70% fiber of cabuya, 45 % latex-55% fiber of cabuya,since compression molds and manual stratification were used for the same. Of the essays carried out, the group of specimens that exhibit the best results in their mechanical properties through the tests under the UNE standard. (UNE - ISO 37, UNE - ISO 7743, UNE - ISO 48). With the analyzes developed by means of the statistical methodology based on the general complete factorial design and the function of desirability, it was determined that the best mechanical characteristics of the composite material to take advantage of, It was composed of fiber length of 1cm and volumetric fraction of 20% Latex - 80% Cabuya, obtaining results for tensile stress of 10,592 MPa, modulus of elasticity of 9,986 MPa and shore hardness D 48,667.
