Abstract
Aspects of the disclosure are directed to a bonding of a first skin and a second skin to a core material, coupling a sheet to the first skin to form with the first skin an enclosure containing the second skin and the core material, exposing the first skin, the second skin, and the core material to heat, and based on the exposition of heat, applying pressure via the enclosure to the first skin to cause the first skin to deform and expand to a shape of a die.
Claims19
A method comprising:
- bonding a first skin and a second skin to a core material, wherein the core material comprises a honeycomb core;
- coupling a sheet directly to the first skin to form with the first skin an enclosure between the sheet and the first skin, the second skin and the core material arranged within the enclosure and between the sheet and the first skin;
- exposing the first skin, the second skin, and the core material to heat;
- and
- based on the exposition of heat, applying pressure via the enclosure to the first skin to cause the first skin to deform and expand to a shape of a die.

A method, comprising:
- bonding a first skin and a second skin to a core material, wherein the core material comprises a plurality of cavities that extend completely through the core material between the first skin and the second skin;
- coupling a sheet to the first skin to form with the first skin an enclosure in which the second skin and the core material are positioned, wherein the second skin and the core material are between the first skin and the sheet, and the coupling between the sheet and the first skin is independent of the second skin and the core material;
- heating the first skin, the second skin and the core material;
- and
- applying pressure via the enclosure to the first skin to cause the first skin to deform and expand to a shape of a die, wherein the die contacts the first skin.
