FUSELAGE BURN-THROUGH BLOCKING MATERIAL

摘要

A fuselage burn-through blocking material includes a layer of a 30 to 300 g/m non-woven material of needled, flame retardant fibres laminated to one or both surfaces of a 100 to 600 g/m isachieved by a partially cross-linked, latently adhesive, heat resistant binder included in the mica paper itself. The process for manufacture of the laminate includes adhesiveconnection of the layers under pressure and at a temperature which does not trigger full cross-linking of the binder. The resulting two or three layer laminate when installed in a fuselage significantly increases the fuselage burn-through time in a post-crash fire to at least 3 minutes.
