Publication number: 20100032064Abstract: A method is disclosed for producing an energetic metastable nano-composite material as well as the energetic metastable nano-composite materials produced thereby. Under pre-selected milling conditions a mixture of powdered components are reactively milled. These components will spontaneously react at a known duration of the pre-selected milling conditions. The milling is stopped at a time at which the components have been compositionally homogenized to produce nanocomposite powder, but prior to said known duration, and thereby before the spontaneous reaction occurs. The milled powder is recovered as a highly reactive nanostructured composite for subsequent use by controllably initiating destabilization thereof.Type: ApplicationFiled: September 28, 2009Publication date: February 11, 2010Inventors: Edward L. Dreizin, Mirko Schoenitz

Patent number: 7638006Abstract: A fluorine gas generating material composition comprises a fluorine bearing material, the fluorine bearing material releasing fluorine gas at a first temperature, and a coruscative material, a reaction temperature of the coruscative material equal to or greater than the first temperature. In some embodiments, the fluorine bearing material is a nickel-based alloy and the coruscative material includes an element from Group IVB, VB or VIB of the periodic table or a transition metal and a carbon-based material. The fluorine gas generating material composition can be incorporated into a product such as a munition, a flare, a shape charge or an impulse device. The disclosed fluorine gas generating material composition can be used to produce work in applications and methods that include point delivery of fluorine gas, explosives related applications, aerospace applications, and applications in the fields of mining and drilling.Type: GrantFiled: August 23, 2004Date of Patent: December 29, 2009Assignee: Lockheed Martin CorporationInventor: James R.

Patent number: 7632364Abstract: An energetic composite material is provided that includes inorganic particles and self-assembled monolayers (SAMs) formed on the inorganic particles. The SAMs include multifunctional linking molecules and optionally non-linking molecules. The multifunctional linking molecules have linking functional groups respectively chemically bonding to a corresponding pair of the inorganic particles so that the multifunctional linking molecules interconnect the inorganic particles to one another to form a network of inorganic particles. The optional non-linking molecules include a non-linking functional group chemically bonded to a corresponding one of the inorganic particles. Preferably, the multifunctional linking molecules and/or the optional non-linking molecules are fluorinated. Also preferably, bare aluminum particles are selected as the inorganic particles and are passivated with the SAMs.Type: GrantFiled: November 10, 2004Date of Patent: December 15, 2009Inventors: Richard Jason Jouet, Andrea D. Warren, Thomas P. Russell
