Vegetable fibers have been used in several economic sectors as a substitute for synthetic fibers. Among the advantages of using vegetable fibers are low cost, toxicity and density. These rigid particles added to the polymers increase the modulus of elasticity and thermal conductivity of the composite as well as increase its toughness. The present work aims to present the results of the mechanical analysis of the hybrid polymer composite with reinforcement of banana fibers and copper beneficiation residue. The banana fibers were cut to 15mm length, and the composites were made manually at ambient temperature under pressure and using a standardized metal mold. The samples were mechanically characterized by the bending test. The polymer composites were manufactured following the proportions: hybrid composite banana fiber / copper residue (1/10; 1/20; 1/30; 2/10; 2/20; 2/30; 3/10; 3/20 , 3/30 wt.%). The best obtained results of maximum bending stress were obtained from reinforced composites with a 3% fraction of banana fiber and 20% copper residue [71.1 MPa] and the composite with 2% fiber fraction and 30% copper residue [67.7MPa].
