The curauá fiber, a bromeliad (Ananas erectifolius LB Smith), is considered large in the Amazon region, its mechanical properties of high strength, low density - capable of giving lightness to the final product - and potential for recycling, is listed for replace the fiberglass used as reinforcement to the plastic in the manufacture of parts with reduced features and detailed, produced by injection molding process, such as cars panel buttons, knobs and hinges. The materials used for manufacturing the polymer composites were curauá fibers acquired commercially from Belém in nature form, and a matrix of polyester resin terephthalic unsaturated and pre-accelerated chosen from one of the proportions of 0.33% (v / v), 1.66% (v / v), 3.33% (v / v) and 5% (v / v) which was initially studied. In the manufacture of the composite resin was used in combination with curauá fibers with lengths of 10 mm and a mass fraction of 3.87%, 4.87% and 5.87%.
