Abstract

PROCESO PARA FABRICAR ESTRUCTURAS DISTRIBUIDAS EN CAPAS INDIVIDUALES (14) QUE COMPRENDE LAS FASES: A) INCORPORACION DE UNA ESTRUCTURA CONTINUA DISTRIBUIDA EN CAPAS EN FORMA DE MALLA QUE POSEE UNAS REGIONES DE CORTE DISEÑADAS A TAL EFECTO, Y QUE LLEVAN INCORPORADAS UN MATERIAL CON PARTICULAS (6,9) ENTRE LAS CAPAS DE CONTENCION, Y AL MENOS UNA DE LAS CAPAS ES PERMEABLE A LOS LIQUIDOS; EL PROCESO COMPRENDE ADEMAS LAS FASE DE: B) APLICACION DE UN MATERIAL TERMOPLASTICO EN FORMA LIQUIDA A LA ESTRUCTURA CONTINUA DISTRIBUIDA EN CAPAS EN FORMA DE MALLA, AL MENOS SOBRE PARTE DE DICHAS REGIONES DE CORTE, PARA QUE EL MATERIAL TERMOPLASTICO SE UNA A LAS CAPAS DE CONTENCION ALLI DONDE SE APLIQUE. C) DEJAR QUE EL MATERIAL TERMOPLASTICO SE FIJE, Y D) CORTE DE LA ESTRUCTURA CONTINUA DISTRIBUIDA EN CAPAS EN FORMA DE MALLA EN LAS REGIONES DE CORTE DISEÑADAS A TAL EFECTO, PARA OBTENER LAS ESTRUCTURAS DISTRIBUIDAS EN CAPAS INDIVIDUALES (14). TAMBIEN SE DESCRIBE UNA ESTRUCTURA DISTRIBUIDA EN CAPAS INDIVIDUAL (14) QUE PUEDE OBTENERSE CON ESTE PROCESO.
