  • Patent number: 8206522
    Abstract: A non-toxic, non-hydroscopic percussion primer composition and methods of preparing the same, including at least one explosive component that has been traditionally considered a moderately insensitive explosive or secondary explosive, and at least fuel particle component having a particle size of about 1.5 microns to about 12 microns, which allows the use of moderately active metal oxidizers. The sensitivity of the primer composition is created by the interaction between the moderately insensitive explosive and the fuel agent such that traditional primary explosives such as lead styphnate or DDNP are not needed. The primer composition also eliminates the risks and dangers associated with traditional nano-sized fuel particles.

    Abstract: The present invention discloses materials, systems and methods for creating metal foams to envelop targets, which involve the formulation of powdered thermite/metal matrices. Essentially, each matrix will include thermite and a foaming agent. Additionally, a thickening agent can be blended into the powdered thermite/metal matrix to create desirable foaming properties when the thermite is ignited. A heat sink agent can also be dispersed throughout the powdered thermite/metal matrix to limit temperature rise in the matrix during a thermite reaction. Further, a binder can be combined with the powdered thermite/metal matrix to hold the formulation together. In use, the formulation is delivered to the vicinity of the target where it is ignited. The resultant metal foam is intended to envelop and neutralize the target.

    Abstract: 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.

  • Publication number: 20100143851
    Abstract: A thermite torch formulation that consists essentially of a metal fuel, a first oxidizer CuO, a second oxidizer MoO3, and a binder material. When the thermite formulation is reacted, a torch may direct at least one reaction product onto a certain region of an object to deliver a large amount of energy to that region of the object.

  • Patent number: 7670446
    Abstract: A method is disclosed for preparing metastable nanoenergetic composites (MNC) and for wet loading those MNCs into percussion primer cups. The method involves dispersing nanosize reactants in an inert liquid or, alternatively, making a nanosize reactant surface modification for improvement of reactant's chemical inertness towards water, followed by application of additives supporting a solid reactant particle dispersion in water or water solution prior to mixing. After mixing of the reactants, one maintains the presence of liquid water together within an energetic material in order to enhance safety during pre-loading of the primer mixture into the primer cups and during the final drying.

  • Publication number: 20100032064
    Abstract: 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.

  • Patent number: 7632364
    Abstract: 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.
