Flexible composite multiple layer fire-resistant insulation structure

A flexible composite multiple layer burn-through resistant insulation structure, comprising:

• at least a first lofted insulative layer, positioned adjacent to;
• at least a dimensionally stable membrane positioned adjacent to;
• at least a first woven fabric facing layer, positioned adjacent to;
• at least a second lofted insulative layer.

An aircraft fuselage having an outer surface, a plurality of structural members, and an inner surface, comprising;

• a flexible composite multiple layer fire-resistant insulation structure disposed between the fuselage outer surface and the fuselage inner surface and substantially filling the space between at least two structural members;
• wherein the structure further has a woven fabric facing layer disposed towards the fuselage outer surface;
• and
• a lofted insulative layer disposed towards the fuselage inner surface;
• and
• a dimensionally stable membrane adjacent to at least one layer chosen from the layers consisting of the facing layer and the lofted insulative layer.

A method of manufacturing a flexible composite multiple layer fire-resistant insulation structure, the steps comprising;

• a) providing a woven fabric outer layer having an outer facing surface and an inner facing surface;
• b) applying a high-phosphate heat-resistive treatment to at least one surface of the woven fabric outer layer;
• b) disposing a dimensionally stable membrane having an outer membrane surface and a membrane inner surface such that the outer membrane surface is disposed on the inner facing surface;
• c) disposing a lofted insulative layer having an outer insulative surface and an inner insulative surface such that the outer insulative surface layer is disposed on the inner film;
• and
• d) enclosing the woven fabric, acoustic film, and lofted insulative layer in an abrasion resisting outer covering.
