Abstract
One aspect of a process of forming an aircraft component includes bonding a first end of a honeycomb structure to a surface of an aircraft skin member, the honeycomb structure including multiple connected cells. Foam is sprayed on a second end of the honeycomb structure opposite the first end. The process also includes curing the foam on the second end of the honeycomb structure.
Claims20
A method of forming an aircraft component, the method comprising:
- bonding a first end of a honeycomb structure to a surface of an aircraft skin member, the honeycomb structure comprising a plurality of connected cells;
- spraying foam on a second end of the honeycomb structure, the second end opposite the first end;
- and
- curing the foam on the second end of the honeycomb structure.

A method of forming an aircraft component, the method comprising:
- bonding a first end of a honeycomb structure to a surface of an aircraft skin member, the honeycomb structure comprising a plurality of connected cells, each cell comprising a plurality of surfaces, wherein adjacent cells share a common vertical surface;
- spraying foam in a fluid state on a second end of the honeycomb structure, the second end opposite the first end;
- and
- curing the foam on the second end of the honeycomb structure from the fluid state to a solid state to bond the foam in the solid state to the aircraft skin member.

A method of forming an aircraft component, the method comprising:
- spraying foam in a liquid state on a first end of a honeycomb structure bonded to a second end of a surface of an aircraft skin member, the second end opposite the first end, the honeycomb structure comprising a plurality of connected cells;
- and
- curing the foam in the liquid state on the second end of the honeycomb structure to a solid state to bond the foam to the aircraft skin member.
