<p>A semi-rigid, light weight insulation blanket (20) is composed of a skeleton (12) having porous cavities sandwiched between layers of fiber glass (10). The polyimide foam skeleton (12) prevents sagging particularly in crown and upper sidewall areas of an aircraft thereby maintaining a predetermined offset from the skin fuselage reducing corrosion of the primary structure from moisture condensate. This configuration provides similar acoustic performance with reduced weight.</p> |
