SEMI-RIGID, LIGHT WEIGHT FIBER GLASS/POLYIMIDE FOAM SANDWICH BLANKET INSULATION

A semi-rigid, light weight insulation blanket is composed of a skeleton having porous cavities sandwiched between layers of fiber glass. The polyimide foam skeleton prevents sagging particularly in crown and upper sidewall areas of an aircraft thereby maintaining a predetermined offset from the skin...

More Information
Summary:A semi-rigid, light weight insulation blanket is composed of a skeleton having porous cavities sandwiched between layers of fiber glass. The polyimide foam skeleton 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.
