Aramid-based honeycomb core

To obtain the best balance between waU thickness and electrical performance many radomes currently utilise simple honeycomb sandwich structures in their construction. The composite skins are quartz, glass or aramid (generally Kevlar) reinforced epoxy mouldings carbon reinforcement is not used within the window area of a radome because of the poor dielectric constants associated with these structures. Epoxy-based film adhesives are used to bond these skins to the Nomex honeycomb core and/or semi-structural foam.
