Caracterización mecánica del material compuesto de matriz poliéster con fibra de coco para la determinación de propiedades mecánicas en aplicaciones industriales

Abstract

The present experimental project is based on the determination of mechanical properties of a composite material based on polyester resin reinforced with coconut fiber, in various configurations, fiber volumetric fraction and stratification, in order to establish the ideal combination that provides the best Mechanical properties of the composite for the most suitable application in the industry. Flexural, tensile and impact tests were developed under ASTM-3039, ASTM-7264 and ASTM-5628 standards. The specimens were made in a welded steel matrix, with dimensions specified in standards, with a surface finish suitable for the perfect development of the test specimens, the resin was prepared in conjunction with MECK at 2% of its volume, And the fiber was manually extracted from dried coconuts with a cleaning treatment with Sodium Hydroxide. The data were tabulated and their selection of the best combination of the samples made being the best combination of short fiber at 30% in volumetric fraction, in random orientation and manual stratification, presenting good mechanical properties, an acceptable energy absorption in the tests and good distribution of stress throughout the material The industrial applications found for our material were seen in the realm of the construction industry, the furniture industry and the automotive industry.
