Honeycomb core composites encompass lightweight sandwich-structure materials built around cellular core geometries — typically hexagonal, over-expanded (OX), or flex-core configurations — manufactured in aluminium alloy, aramid-fibre paper (Nomex), fibreglass, or thermoplastic, and bonded to structural face sheets using film adhesives under autoclave or press-cure processes to achieve high stiffness-to-weight ratios for aerostructure applications.
