Obtención de un material compuesto de matriz poliéster y lana de oveja para evaluar el comportamiento mecánico

Abstract

The production of sheep wool is one of the natural resources that are not used at present, its cost is relatively low and friendly to the environment, so in the present experimental project a composite material was developed that is based on a polyester resin matrix and reinforcement configuration of sheep wool, in which two types of volumetric fractions were taken 70% matrix - 30% reinforcement and 60% matrix - 40% reinforcement, two types of configurations were also made of reinforcement: discontinuity to the longitudinal axis and discontinuity to the transverse axis. The manufacturing of the specimens was carried out in a compression steel mold. The tensile and bending tests were carried out in the Metalmecánico Carrocero Productive Production Center and the impact test was carried out in the Materials Laboratory of the Faculty of Civil and Mechanical Engineering. By means of tensile, bending and impact tests performed on the specimens and under ASTM D3039-00, ASTM D7264-07 and ASTM D5628-10 standards respectively, the composite material that obtained the best mechanical characteristics was determined, being this group 2 the which is composed of 70% polyester matrix and 30% sheep wool, with a configuration of discontinuity to the transverse axis.
