Claims
- 1. A heat-generating pyrotechnic article in the form of a carbon fiber web hot over about one millimeter thick, bent to provide portions that block the open radiation of heat from other portions sufficiently to increase the heat-generating time at least about 60% as compared to when the web is not bent.
- 2. The article of claim 1 in which the web carries pyrophoric metal in a quantity sufficient to pyrophorically ignite when exposed to air, and to then ignite the carbon fiber.
- 3. A heat-generating pyrotechnic article in the form of a web not over about one millimeter thick, the web having cemented to its surface a porous layer about 20 to about 500 microns thick of finely divided silica, alumina or zirconia or mixtures of them.
- 4. The article of claim 3 in which the web is a carbon fiber cloth that also carries pyrophoric powder.
- 5. In the process of discharging carbon fiber web to decoy heat-seeking objects, the improvement according to which the web is the web of claim 1.
- 6. In the process of discharging carbon fiber web to decoy heat-seeking objects, the improvement according to which the web is the web of claim 2.
