Abstract
A formation method is provided during which a cellular core is provided. The cellular core includes a plurality of cavities that include a first cavity. Each of the cavities extends through the cellular core. A metal substrate is disposed within the first cavity. The metal substrate is electroplated to form a septum within the first cavity. The septum is bonded to the cellular core.
Claims18
A formation method, comprising:
- providing a cellular core, the cellular core comprising a plurality of cavities that include a first cavity, each of the plurality of cavities extending through the cellular core;
- disposing a metal substrate within the first cavity;
- electroplating the metal substrate while the metal substrate is disposed within the first cavity to form a septum within the first cavity;
- bonding the septum to the cellular core;
- and
- forming an acoustic panel, the acoustic panel comprising a core structure between a perforated first skin and a second skin, and the core structure comprising the cellular core and the septum.

A formation method, comprising:
- forming a core structure comprising a cellular core and a septum, the cellular core comprising a first cavity that extends through the cellular core, the septum comprising a first metal layer, a second metal layer and one or more perforations extending through the first metal layer and the second metal layer, and the septum disposed within the first cavity and bonded to the cellular core;
- wherein the forming comprises disposing the first metal layer within the first cavity;
- and
- electroplating the first metal layer while the first metal layer is disposed within
- the first cavity to form the septum within the first cavity;
- arranging the core structure between a perforated first skin and a second skin;
- and
- bonding the core structure to the perforated first skin and the second skin to form an acoustic panel,
- wherein the cellular core comprises a honeycomb core.
