[ES] Los nanocomposites son nuevos materiales avanzados en los que se combina una matriz de carácter orgánico, metálico o cerámico, con un refuerzo de diferente naturaleza de tamaño nanométrico , ya sea de tipo nanolaminar , nanoesférico o nanofibroso . En esta Tesis Doctoral el material seleccionado como matriz de los nanocomposites es la poliamida 66 (PA66) y como refuerzo inorgánico la sepiolita organofilizada. Se han fabricado nanocomposite s mediante la técnica de mezclado en fundido por extrusión. Los diferentes porcentajes en peso de sepiolita son: 1, 3, 5, 7 y 9 %. Las propiedades mecánicas , térmicas y cristalográficas, la nueva estructura cristalina del nanocompo site, la dispersión de la sepiolita dentro de la matriz y las propiedade s tras diferentes procesos oxidativos de degradación han sido objeto de estudio a lo largo de esta Tesis Doctoral
[EN]Nanocomposites are new advanced material s in which a matrix , organic, metal or ceramic, is combined with a nanometric reinforcement of different nature, whether nanolaminate , nanofibrous or nanospherical. In this PhD Thesis, the material selected as matrix is polyamide 66 (PA66). Organophilized sepiolite was used as inorganic reinforcing . Nanocomposites were manufactured via melt intercalation using an extruder. Different weight percentages of sepiolite are: 1, 3, 5, 7 and 9%. Studies on mechanical , therm al and crystallographic properties, new crystal structure of the nanocomposite, dispersion of sepiolite within the matrix and properti es after different oxidative degradation processes have been carried out in this PhD Thesis.
