Caracterización de las propiedades mecánicas del material híbrido utilizando matriz epóxica reforzada con tejido de fibra vegetal de algodón y fibra natural de abacá

Abstract

This experimental research is based on the characterization of the hybrid material of epoxy matrix reinforced with layers of structured woven of abaca fibers and cotton in different orientations and with varied volumetric fractions, the purpose of the study is to obtain the best characterization of the material containing the best mechanical properties. In this work the stratification process was used for compression to obtain the hybrid material, it was to establish the definitive percentage volumetric fractions of reinforcements, material thickness and number of layers of reinforcement of woven. Of all the characterizations made determined group of specimens that exhibits the best mechanical properties tests standardized under the ASTM standards. (ASTM D3039-00 traction, flexion ASTM D7264-07 and impact ASTM D5628-10). The analysis of three types of trials determined that the hybrid material presented better mechanical properties corresponds to the case 3 which has a volumetric fraction of 75% resin Epoxy (matrix), 18.25% abaca fiber and 6.75 percent cotton (reinforcements).
