Abstract
An extrudable black body decoy flare composition which, when combusted, provided black body radiation is disclosed. The compositions generally include from about 40% to about 70% metal such as magnesium or aluminum, from about 10% to about 40% polytetrafluoroethylene, and from about 8% to about 30% binder. Important to the operation of the invention is the production of carbon upon combustion of the composition. Accordingly, polyaromatic thermoplastics, such as polystyrene and dimethyl phthalate, serve as the binder.
Claims19
A method of producing a black body decoy flare, the method comprising the steps of:
- a. preparing a mixture comprising magnesium, polytetrafluoroethylene, and a polyaromatic thermoplastic binder;
- and
- b. extruding the mixture into a flare grain form.
A method of producing a black body decoy flare, the method comprising the steps of:
- a. preparing a mixture comprising magnesium present from about 40% to about 70% by weight, polytetrafluoroethylene present from about 10% to about 40% by weight, and a polyaromatic thermoplastic binder present from about 8% to about 30% by weight;
- and
- b. extruding the mixture into a flare grain.
An extrudable black body decoy flare composition comprising:
- from about 40% to about 70% by weight magnesium;
- from about 10% to about 40% by weight polytetrafluoroethylene;
- and
- from about 8% to about 30% by weight polyaromatic thermoplastic binder.
A black body decoy flare composition comprising:
- from about 40% to about 70% by weight magnesium,
- from about 10% to about 40% by weight polytetrafluoroethylene;
- and
- from about 8% to about 30% by weight binder;
- wherein the binder comprises polystyrene present from about 20 to about 100 weight percent of the binder and dimethyl phthalate present at up to 80 weight percent of the binder.
