Abstract

SE PRESENTA UNA ESTRUCTURA DE ESPUMA DE PLASTICO DE CELULAS CERRADAS QUE COMPRENDE UNA ESPUMA DE PLASTICO (10) QUE DEFINE UNA MULTIPLICIDAD DE CANALES (30) QUE SE EXTIENDEN DESDE LA SUPERFICIE DE LA ESPUMA HASTA DENTRO DE LA ESPUMA. LOS CANALES ESTAN LIBRES DE DIRECCION RESPECTO DE LA EXTENSION LONGITUDINAL DE LA ESPUMA Y PREFERENTEMENTE PERPENDICULARMENTE A LA EXTENSION LONGITUDINAL A LA ESTRUCTURA DE LA ESPUMA. LOS CANALES ESTAN EN COMUNICACION GASEOSA CON EL AMBIENTE EXTERIOR DE LA ESTRUCTURA DE ESPUMA, Y PROPORCIONAN UNA LIBERACION REALZADA DE AGENTES DE INFLADO. ADEMAS SE PRESENTA UN PROCESO PARA FABRICAR UNA ESTRUCTURA DE ESPUMA DE PLASTICO QUE CONSISTE EN (A) PROVEER UNA ESPUMA DE PLASTICO Y (B) PERFORAR LA ESPUMA EN SU SUPERFICIE PARA FORMAR UNA MULTIPLICIDAD DE CANALES QUE SE EXTIENDEN DESDE LA SUPERFICIE HASTA DENTRO DE LA ESPUMA PARA FORMAR LA ESTRUCTURA DE ESPUMA.
