Abstract
A method of manufacturing an acoustic structure is disclosed. An adhesive material and a septum forming material may be deposited on a first honeycomb ribbon. A second honeycomb ribbon may be adhered to the adhesive material and the septum forming material. The first honeycomb ribbon and the second honeycomb ribbon may be expanded to form a honeycomb structure. The septum forming material may stretch or expand to form a septum cap in a cell of the honeycomb structure. The septum forming material may be inherently porous, and/or the septum cap may be cured in order to introduce pores into the septum cap.

A method of manufacturing an acoustic structure comprising:
- applying an adhesive to a first honeycomb ribbon;
- applying a septum forming material to the first honeycomb ribbon;
- adhering a second honeycomb ribbon to the adhesive and the septum forming material;
- and
- expanding the first honeycomb ribbon and the second honeycomb ribbon into a honeycomb structure.
A method of manufacturing an acoustic septum comprising:
- adhering a first substrate to a second substrate with a septum forming material;
- and
- separating the first substrate from the second substrate;
- wherein the septum forming material stretches to form an acoustic septum cap between the first substrate and the second substrate.
