    This work was carried out to investigate the possibility of using animal fiber as a reinforcement in a polymeric material. The beef hair was obtained from the municipal abattoir of the city of Ambato that, not being used by the industry, becomes waste, which makes it attractive due to the easy availability and low cost, proving to be an alternative to synthetic fibers. The present investigation is based on the mechanical characterization of polyester matrix composite material reinforced with beef hair fiber, for which specimens were elaborated with volumetric fractions of 60 percent matrix and 40 percent reinforcement, also with 70 percent matrix and 30 percent reinforcement. Long fiber was used with a longitudinal orientation at 0 degrees and 45 degrees, short fiber (10mm) with a randomly crisscrossed distribution. These specimens were tested to traction, flexure and impact under the specifications of ASTM D3039, ASTM D7264 and ASTM D5628 respectively, in order to determine the most suitable mechanical properties of the composite material and to be able to give use in the industry. From the analysis of the 6 groups of specimens that were subjected to their respective tests, it was determined that the composite material that presented the best results corresponds to group 1 which has a volumetric fraction of 60 percent matrix and 40 percent reinforcement, with a long fiber configuration oriented to 0 degrees, obtaining a maximum tensile strength of 30.87 MPa , maximum to bending resistance of 55 MPa and 1.02 J of impact energy. It was also determined that this material can be applied in the automotive industry and in the furniture construction.
