Abstract
A method of fabricating and using a honeycomb core structure for aircrafts. The honeycomb core structure may comprise a septum positioned within and integral to a honeycomb core. The method may comprise sandwiching the septum between two sections of a die. Each section of the die may comprise a plurality of spaced apart columns, each having a hexagonal cross-section. The method may further comprise injecting melted thermoplastic throughout both sections of the die between the columns and cooling the thermoplastic, thereby hardening and integrating the thermoplastic and the septum together to form the honeycomb core structure. The method may also comprise affixing the honeycomb core structure within an aircraft structure to provide a structural load path for a primary component of the aircraft.
