The production of composite materials reinforced with vegetable fibers was evaluated in a polymeric matrix consisting of teraphthalic unsaturated polyester resin. The manufacturing process was hand lay-up in the presence of Oil Palm (Elaeis guineenses). The mechanical characterization of the composites was studied through tensile tests. The fibers used in the experiment were in natura and chemically treated condition with 10% sodium hydroxide under ultrasonic agitation. For the verification of the strength and stiffness of the samples, universal test machines were used. The tensile test of specimens reinforced with discontinuous fibers and randomly oriented fibers was used, using lengths of 5, 10, 15 mm, for mass fractions varying according to the volumetric capacity of the silicone mold. In addition, a fractographic analysis was performed in the scanning electron microscope. In some cases, the results indicated that the mechanical properties of the composites increased with the chemical treatment of natural fibers.
