Abstract

ES OBJETO DE LA INVENCION UN PROCESO PREFERENTEMENTE DE ESTRUCTURAS DE FIBRAS TEXTILES, CUYAS FIBRAS CONTIENEN, CON DIFERENTES PROPIEDADES TERMICAS POR PRESION, CALOR Y AIRE CALIENTE HUMEDO, Y CON HERRAMIENTAS QUE MUESTRAN A SER POSIBLE UNA POROSIDAD UNIFORME, PLACAS Y FORMAS PERFILADAS CON UNA ESTRUCTURA DE SANDWICH PARA PRENSAR Y SIGUIENDO EL MISMO CICLO, ENFRIAR, EN DONDE SE CONSEGUIRA MEDIANTE EL AIRE CALIENTE HUMEDO Y UN DIMENSIONAMIENTO ESPECIAL DE LA HERRAMIENTA UNA SOBRECARGA EN LA HERRAMIENTA Y POR CONSIGUIENTE EN LA ESTRUCTURA FIBROSA, QUE SE SOLIDIFICARA EN GRAN PARTE DE FORMA UNIFORME EN LAS SUPERFICIES DE LA HERRAMIENTA, DONDE LA ESTRUCTURA INTERNA DE LAS FORMAS PERFILADAS Y PLACAS MUESTRA ENTONCES UN PESO POR UNIDAD CUBICA INFERIOR. MEDIANTE LA APLICACION DE ESTE PROCESO PODRAN REDUCIRSE LOS PESOS DE LAS PIEZAS PERFILADAS Y DE LAS PLACAS REPRESENTADAS, LO QUE YA SOLO EN PRECIO Y ACEPTACION EN EL MERCADO, SEGUN LOS FUNDAMENTOS ENERGETICOS, ES DE UNA IMPORTANCIA DECISIVA. MEDIANTE APLICACION DE SISTEMAS DE FIBRAS CON UNIFORMIDAD POLIMERA SE DA ADEMAS UNA RECUPERACION DEBIDO A QUE ENTONCES SE PUEDE RENUNCIAR A SISTEMAS DE UNION EXTRAÑOS.
