Abstract

ELEMENTO DE MATERIAL ESPONJOSO PARA LA INSONORIZACION DE CAVIDADES, ESPECIALMENTE DE PERFILES EXTRUIDOS DE METAL LIGERO, COMO SE UTILIZAN EN LA CONSTRUCCION DE VEHICULOS SOBRE CARRILES. EL ELEMENTO DE MATERIAL ESPONJOSO SEGUN LA INVENCION (1) COMPRENDE UN SANDWICH DE MATERIAL ESPONJOSO DE, AL MENOS, DOS CAPAS, DE UNA CAPA FLEXIBLE (11) Y, AL MENOS, DE UNA CAPA PESADA (12) QUE SE APLICA EN LA CAPA FLEXIBLE (11). LA CAPA FLEXIBLE (11) SE COMPONE, ESPECIALMENTE, DE ESPUMA BLANDA DE POLIURETANO Y LA CAPA PESADA (12) SE COMPONE, ESPECIALMENTE, DE ESPUMA COMPUESTA DE FLOCOS DE POLIURETANO. EL ELEMENTO DE MATERIAL ESPONJOSO SEGUN LA INVENCION (10) SE SUELDA, ANTES DE LA INTRODUCCION EN UNA CAVIDAD A INSONORIZAR (22), EN UNA LAMINA IMPERMEABLE AL AIRE (13) DE UNA FORMA TAN COMPRIMIDA QUE SE PUEDE INTRODUCIR EN LA CAVIDAD A TRAVES DE UNA ABERTURA (21) DE LA CAVIDAD (22). DESPUES DE LA INTRODUCCION Y COLOCACION DEL ELEMENTO DE MATERIAL ESPONJOSO (10) SE ABRE LA LAMINA (13), EXPANDIENDOSE EL ELEMENTODE MATERIAL ESPONJOSO (10) CON LA APORTACION DE AIRE, DE MANERA QUE AL MENOS UNA CAPA PESADA (12) SE AJUSTE DE FORMA FUNDAMENTALMENTE SUPERFICIAL A LAS PAREDES (23) DE LA CAVIDAD (22) COMO CONSECUENCIA DE LA PRESION EJERCIDA POR LA CAPA ELASTICA.
