[en] Until recently, it has become important to develop more durable plastic materials to meet the needs of the market, which have wide range of applications. But these materials are from non-renewable sources cause environmental impact due to the large amount of waste they produce. In order to evaluate the effect of organoclay (Brasgel PA and vermiculite) and impact modifier (EMA-GMA) were developed PLA bionanocomposites / Clays through the merge process by melting and rated the content (1, 3 and 5pcr) the mechanical properties of these clays. The clays were organophilizated using a percentage of surfactant based on the capacity of cation exchange. The bionanocomposites were prepared by extrusion followed the injection molding step of the specimens. The clays were characterized by X-ray diffraction (XRD).The bionanocomposites were characterized by the mechanical properties of impact and traction. The techniques of X-ray diffraction showed that organophilization process used was efficient. The mechanical properties were changed, and the impact strength showed considerable gain when the PLA was blended with the copolymer and the organoclay. (author)
