Abstract
A base fabric for a radar defeating camouflage material comprising a knitted fabric knitted from a plurality of strands to form a stretchable, flexible fabric having a plurality of openings therethrough, each of these strands constituting a spun mixture of noncontinuous polymeric fibers and noncontinuous metal or carbon fibers. The fibers can be nylon or polyester. The metal fibers can be stainless steel. The metal or carbon fibers can comprise about 2 - 10 percent by weight of the spun yarn, the fibers having an average diameter between about 0.008 and 0.02 millimeters and an average length between about 50 millimeters and 90 millimeters.
Claims7
An improved radar-defeating, flexible camouflage material comprising
- a base fabric comprising a plurality of strands of spun yarn knitted together to form a stretchable, flexible, substantially planar fabric having a plurality of openings therethrough,
- each of said strands comprising a spun mixture of polymeric fibers and noncontinuous electrically conductive fibers with said conductive fibers comprising about 2 to 10 percent of the spun yarn, by weight to cause said base fabric to exhibit radar reflectance characteristics similar to its natural surrounding environment;
- a first flexible film covering and adhered to one surface of said fabric, and
- a second flexible film covering and adhered to the other surface of said fabric,
- said first and second films being adhered to each other through said openings in said fabric.
