BURN THROUGH RESISTANT SYSTEMS FOR TRANSPORTATION, ESPECIALLY AIRCRAFT

摘要

An encapsulated insulation composite system for increasing the bum through resistance of an aircraft fuselage includes: an insulation layer of glass fiber or foam insulation and a coating or interleaf barrier layer of a high temperature resistant material and/or a coating or barrier layer of a high temperature resistant material on an outer major surface of the insulation layer of the composite and a film encapsulating the composite. Preferably, the barrier layer or layers include a reflective mineral, such as a reflective mineral containing coating carried on a sheet material. Preferably, the encapsulating film is a polymeric film such as a~ polyimide film.
