Abstract
A structure is provided comprising carbonaceous materials for absorbing and/or reflecting radiated energy or electromagnetic energy. The structure is useful for camouflage or for shielding electromagnetic radiation, especially microwaves.
Claims28
In a structure for absorbing and/or reflecting radiated energy or electromagnetic radiation, the improvement which comprises 1) means for absorbing incident radar waves for reducing target signature and 2) at least one layer of a non-flammable fluorinated or non-fluorinated carbonaceous material having a LOI value of at least 40 for absorbing radiant energy, said carbonaceous material consisting of at least one of foam, film, linear and non-linear non-graphitic fibers and non-linear graphitic fibers.
A camouflage structure for attenuating infrared radiation, comprising at least one flexible layer of a flexible electrically non-conductive non-flammable fluorinated or non-fluorinated carbonaceous material consisting of at least one of film, foam, linear and non-linear non-graphitic fibers and non-linear graphitic fibers, at least one flexible layer of an electrically conductive material for absorbing electromagnetic waves and means for providing a three dimensional effect for radar radiation.
A camouflage material for military targets effective in the range from visible light to radar waves comprising 1) means or absorbing incident radar waves for reducing target signature and 2) at least one layer of an effective amount of radar absorbing carbonaceous material having electrical conductivity consisting of at least one of foam, film, linear and non-linear non-graphitic fibers and non-linear graphitic fibers.
A flexible camouflage structure which provides a three dimensional effect having ignition resistant and fire resistant properties comprising at least one flexible layer of an electrically conductive non-flammable fluorinated or non-fluorinated carbonaceous material having a LOI greater than 40 for absorbing electromagnetic waves, said carbonaceous material consisting of at least one of foam, film, linear and non-linear non-graphitic fibers and non-linear graphitic fibers and means for providing differing angles for incident and reflected radar waves.
