Abstract

Pyrolyzed carbon fibers are intercalated with alkali metal by contacting fibers with hot metal vapors at a specified temperature to produce an infrared emissive chaff. This chaff can be released into the air to produce a heat generating cloud, which can serve as an infrared decoy or screen to protect military targets against weapons having infrared detectors. The chaff gives off a longer lasting, more moderate heat supply due to the intercalation of its active element, and is much easier to store and handle than prior art pyrophorics.
