Abstract : A thermal barrier compromising a heat responsive intumescent insulating material partially filling open cells in a layer of fire retardent honeycomb material. The thermal barrier is adhesively bonded to the inner surface of an aircraft skin panel. The intumescent material is in thermal contact with the skin and expands in response to heat conducted through the skin. The intumescent material may compromise one or more of a wide variety of matrix systems and fillers. Interior upholstery adhesively bonded to the honeycomb material completes the thermal barrier installation.
