Abstract

SE PRESENTA UN METODO Y UN APARATO PAR LA FORMACION AL VACIO DE REVESTIMIENTOS COMPUESTOS EN CALIENTE. EL APARATO INCLUYE UNA CAMARA DE VACIO ALARGADA (12) QUE TIENE UNA TAPA (14) Y UN ALOJAMIENTO (16). UN SELLAMIENTO INFLABLE (26) SE DISPONE ENTRE LA TAPA Y EL ALOJAMIENTO. EL INFLADO DEL SELLAMIENTO INFLABLE CREA UNA CAMARA DE VACIO IMPERMEABLE AL AIRE. UNA MANTA CALENTADORA (36) SE SITUA EN EL FONDO DE LA CAMARA DE VACIO (12). UNA VEJIGA INFLABLE (28) SE SITUA EN LA PARTE SUPERIOR DE LA MANTA CALENTADORA Y SE EXTIENDE APROXIMADAMENTE SOBRE LA LONGITUD DE LA CAMARA DE VACIO. EL INTERIOR DE LA VEJIGA INFLABLE ESTA CONEXION FLUIDA CON EL EXTERIOR DE LA CAMARA DE VACIO. LAS CARGAS COMPUESTAS (40) SE COLOCAN DENTRO DE LA CAMARA DE VACIO SOBRE LA PARTE SUPERIOR DE LA VEJIGA DE VACIO (28). LOS MANDRILES (42) SE COLOCAN SOBRE LA PARTE SUPERIOR DE LAS CARGAS COMPUESTAS NO FORMADAS Y LA CAMARA DE VACIO SE CIERRA Y SE SELLA. LAS CARGAS COMPUESTAS (40) SE CALIENTAN UTILIZANDO LA MANTA CALENTADORA (36). EL INTERIOR DE LA CAMARA DE VACIO ES EVACUADO EN ESE MOMENTO. A MEDIDA QUE EL INTERIOR ES VACIADO, LA VEJIGA INFLABLE SE EXPANDE FORMANDO LAS CARGAS COMPUESTAS (40) ALREDEDOR DE LOS MANDRILES (42). DESPUES LA FORMACION, LA PRESION EN EL INTERIOR DE LA CAMARA DE VACIO (12) ES EQUILIBRADA Y SE ABRE LA TAPA (14). ENTONCES SE SEPARAN LAS CARGAS COMPUESTAS FORMADAS Y LOS MANDRILES.
