초록 ▼

Conductive carbon fibrils are incorporated into energetic compositions to enhance the burn rate. The carbon fibrils are grown catalytically from carbon precursors and are substantially free of pyrolytically deposited thermal carbon. The fibrils generally have a length in the range from about 1mm

대표청구항 ▼

A method for enhancing the burn rate in an energetic composition selected from propellant and pyrotechnic energetic compositions comprising incorporating into said energetic composition an effective quantity of conductive carbon fibrils sufficient to increase the burn rate at least 20% upon burning said energetic composition, said carbon fibrils having substantially continuous layers of ordered carbon atoms having an outside diameter between about 3.5 and 75 nanometers which are catalytically grown and having a distinct inner core region, each of the carbon layers being disposed substantially concentrically about the inner core region, wherein the fibrils are substantially free of pyrolytically deposited thermal carbon.
