Abstract

"ABERTURAS TERMINAIS DE CONJUNTO DE ALVéOLOS PREENCHIDOS". Um painel tipo sanduíche inclui um núcleo com alvéolos com uma pluralidade de células. A primeira camada é colada a uma primeira superfície do núcleo com alvéolos através de um adesivo. A segunda camada é colada a uma segunda superfície do núcleo com alvéolos com o adesivo. A pluralidade de células se estende longitudinalmente entre a primeira e a segunda camadas. A primeira e segunda camadas são coladas ao núcleo com alvéolos, formando um painel tipo sanduíche tendo uma área de superfície de, pelo menos, 2,25 pés quadrados. Uma espuma de enchimento é disposta dentro das células do núcleo com alvéolos. A espuma de enchimento e o núcleo com alvéolos definem uma primeira região de abertura vizinha à primeira camada e uma segunda região de abertura próxima a segunda camada.
