Beschreibung
Zusammenfassung:	A sandwich acoustic liner assembly includes a honeycomb core and a thermoplastic fabric sheet positioned in overlying relationship and structurally bonded with the honeycomb core. Further included is a method for fabricating a sandwich acoustic liner assembly which includes the steps of positioning a thermoplastic fabric sheet in overlying relationship with a honeycomb core and bonding structurally the thermoplastic fabric sheet to the honeycomb core. Un ensemble de revêtement insonorisant sandwich comprend un noyau en nid dabeille et une feuille de tissu thermoplastique disposée sur le noyau en nid dabeille et lié à celui-ci sur le plan structurel. Il est également décrit une méthode de fabrication connexe qui consiste à positionner une feuille de tissu thermoplastique sur le noyau en nid dabeille et procéder au lien structurel de la feuille de tissu thermoplastique et du noyau en nid dabeille.
