BURNTHROUGH PROTECTION SYSTEM

摘要

A burnthrough protection system including a fire barrier layer, a foam insulation material, and a distinct buffer layer disposed between the fire barrier layer and the foam insulation material, wherein the buffer layer is adapted to prevent adhesion between the fire barrier layer and the foam insulation at elevated temperature. The burnthrough protection system may be capable of passing the flame propagation and burnthrough resistance test protocols of 14 C.F.R. §25.856(a) and (b), Appendix F, Parts VI and VII. Also, an aircraft including an exterior skin, an interior liner, and the burnthrough protection system disposed between the exterior skin and the interior liner.

1. A burnthrough protection system comprising a fire barrier layer, a foam insulation material, and a distinct buffer layer disposed between the fire barrier layer and the foam insulation material, wherein the buffer layer comprises a binder and at least one of boron nitride, vermiculite, mica, graphite, or talc, wherein the buffer layer at least partially prevents adhesion between the fire barrier layer and the foam insulation material at elevated temperature associated with exposure to flame to prevent tears or other defects in the fire barrier layer, and wherein the fire barrier layer forms at least a portion of a covering which at least partially encapsulates the foam insulation material and the distinct buffer layer.
