The present invention relates to the field of coatings on high-energy materials, devices or products that comprise the coated high-energy materials, functional coating materials and methods for producing and using the same. In particular, the present invention relates to energetic materials having initiated release coatings to improve the performance and shelf-life of the devices, products and/or raw materials, suitable for use as energetics or propellants for munitions, rockets, pyrotechnics, flares or other devices or components.

The present invention provides an improved sorbent and corresponding device(s) and uses thereof for the capture and stabilization of volatile organic compounds (VOC) or semi-volatile organic compounds (SVOC) from a gaseous atmosphere. The sorbent is capable of rapid and high uptake of one or more compounds and provides quantitative release (recovery) of the compound(s) when exposed to elevated temperature and/or organic solvent. Uses of particular improved grades of mesoporous silica are disclosed.

The present invention comprises formulations and method for additive manufacturing comprising: a pot-stable photo-curable polymer; one or more fillers; and one or more additives, wherein the formulation cures into a polymer in six hours or less upon exposure to light. In certain examples, the additive manufacturing is a moldless method of additive manufacturing by preparing a formulation comprising: a pot-stable photo-curable polymer, one or more fillers, and one or more additives, and exposing the formulation to light in an amount that substantially cures the polymer in 6 hours or less.

A method for manufacturing nano-sized insensitive high explosive molding powder usable as a booster HE is provided herein. The method preferably involving the steps of dissolving a binder in a liquid and suspending crystalline high explosive to said liquid, grinding that suspension in a bead mill until the crystalline high explosive is nano-sized, and precipitating the binder and crystalline high explosive using a spray dryer to produce granules containing nano-sized crystalline high explosive. The liquid may be water or an organic solvent so long as the binder is highly soluble in the liquid and the crystalline high explosive is generally insoluble in the liquid. A fatty alcohol, water defoaming/dispersant/surfactant agent can be added to the dissolved binder/suspended crystalline high explosive, to aid in the manufacturability.

The present invention relates to a method and installation for loading boreholes with bulk water-based suspension or watergel type explosives characterized by the sensitization of the product by mixing a non-explosive or low sensitivity suspension matrix with compressed gas (e.g. air) at the end of the delivery hose.

An apparatus, system, and method utilizes at least two separate components during the process of producing the final product. At least one component during the process is produced using additive manufacturing, and additional components are components that are combined with the additively manufactured part. The apparatus, system, and method includes at least one energetic component and at least one second inert component. An additive manufacturing system produces a scaffold of said first energetic component(s). A system adds the second component(s) to the scaffold to produce the energetic material product.

Three-dimensional (3D) printed fluoropolymer-based energetic compositions are made using 3D printing methods. The 3D printed fluoropolymer-based energetic compositions comprise a fluoropolymer and a reactive metal or metal oxide. The total weight percentage of the fluoropolymer and the reactive metal or metal oxide is 70-100% of the 3D printed fluoropolymer-based energetic composition, and the weight percentage of the reactive metal or metal oxide is 5-85 wt % of the total weight of the 3D printed fluoropolymer-based energetic material. The 3D printed fluoropolymer-based energetic material has a thickness of at least 200 μm.

A composition that includes a fuel and a perfluoropolyether (PFPE) is disclosed. The composition may be used as a flare composition in a countermeasure device. Countermeasure devices including the flare composition are also disclosed, as are methods of forming grains of the countermeasure device.

The invention relates to a cast explosive composition, particularly to a pre-cure castable explosive composition comprising an explosive material, a polymerisable binder, a microencapsulated cross linking reagent, said microencapsulated cross linking reagent, comprising a cross linking agent encapsulated in a microcapsule.

Explosive compositions for use in high temperature, reactive ground, or both, are disclosed. The explosive compositions can include an emulsion with a continuous organic fuel phase and a discontinuous oxidizer phase. The oxidizer phase can include one or more Group I or Group II nitrates.
