Abstract:
1. An aircraft fire shielding system comprising: a fire-critical aircraft component within a fire risk-zone of the aircraft, the fire-critical component being required to withstand fire for a minimum period of time, the component comprising a body, the system having a protective fire shield covering the body, the fire shield directly exposed to said fire-risk zone and separating said fire-critical component from said fire-risk zone, the protective fire shield having an entirely composite construction composed of fibre cloth impregnated with a sacrificial resin, the sacrificial resin having a melting point that is below that of the fibre cloth, the fibre cloth having a melting point that is above an expected temperature of a fire in the fire-risk zone, such that when directly exposed to fire having a temperature of at least 2000° F. within said fire-risk zone the fibre cloth of the protective fire shield remains substantially intact for at least 15 minutes while the sacrificial resin is allowed to be at least partially consumed by the fire thereby absorbing heat energy and limiting heat transfer to the fire-critical component for at least said minimum period of time.
