Abstract
A manufacturing system to form a honeycomb core and a method of forming the same includes a sheet of fibrous material is fed into a perforation assembly. The sheet of fibrous material is perforated via the perforation assembly to form holes through the sheet of fibrous material. The sheet of fibrous material is cut to form layers. The layers are stacked on top of each other such that the holes of the layers align with each other and strips of adhesive bond the respective layers together to form a perforated stack. A coating is applied to the sheet of fibrous material at the holes. The perforated stack is expanded to form a honeycomb panel. The honeycomb panel is dipped in a solution, and the coating repels the solution. The solution adheres to the honeycomb panel except at the holes where the coating is applied to form the honeycomb core.
