Abstract

A complete seamless honeycomb structure, comprising a coresheet (103) of cell between two facesheets (H1, H2), either in the form of a flat or curved panel. This structure is extruded in a direction perpendicular to the direction of axes of the cells from all combinations of extrudable and mutually fusible materials (142, 143) and completed in one technological sequence without welding, chemical bonding, gluing and the like assembly operations. The method of manufacturing is characterized by continuously extruding a coresheet (103) which is continually deformed in the direction perpendicular to the extrusion into a coresheet (103).
Then, simultaneously and continuously extruding facesheets (H1, H2) and joining them to the coresheet (103), by fusion bonding, while adjoining materials in the zones of connection are still in their mutually fusible state thereby forming a seamless honeycomb structure.
