Fire barrier protection for airplanes comprising graphite films

摘要

A fire barrier system for use in aircraft, ship or offshore drilling platform comprises a flexible graphite sheet. Methods of providing fire barrier protection in an aircraft, ship or offshore drilling platform comprise installing the described fire barrier system in the aircraft, ship or offshore drilling platform. Additionally, the fire barrier system when installed in the aircraft, ship or offshore drilling platform is described.

主权项

1. A method of providing fire barrier protection in an aircraft comprising
a) providing a fire barrier system for use in aircraft comprising a flexible graphite sheet, and b) installing the fire barrier system in the aircraft; wherein the flexible graphite sheet is a continuous film of graphite that has been prepared from a starting material polymer sheet that has been heated to a high temperature for a time sufficient to transform the polymer sheet into a flexible graphitized polymer sheet, and the flexible graphitized polymer sheet has a thermal conductivity in the plane direction of 300 W/mK or more and an Oxygen permeability and/or Hydrogen permeability of less than 5×101 cc/m2·day.
