Abstract:
A composite is provided comprising a polymer matrix including at least one thermoplastic elastomeric polymer (TPE) component, and at least one soft elastomeric polymer component; and a high specific gravity reinforcing filler, and, optionally, carbon black dispersed in the polymer matrix, wherein the composite has a specific gravity of greater than one. The composite is useful in the preparation of: (1) polymeric-based less-lethal ammunition designed to incapacitate the target without inflicting serious or life-threatening injuries; and (2) Drug-eluting electrospun fiber mats for medical applications.
Abstract:
Ammunition for a toy blaster may be infused with or otherwise contain a bittering agent, such as denatonium benzoate. Addition of denatonium benzoate to ammunition formulations may reduce the likelihood that the ammunition may be ingested by children. Ammunition may be formed of a superabsorbent polymer or hydrogel. By introducing a non-toxic bittering agent into the superabsorbent polymer or hydrogel that may form the ammunition, it may be more likely that children may spit out the ammunition instead of swallowing the ammunition. Denatonium benzoate may comprise approximately 50 parts per billion of the superabsorbent polymer or hydrogel, but may comprise approximately 1 to 100 ppb. When used in these low concentrations, the ammunition may be safe for a child to put in his/her mouth, but given the taste of denatonium benzoate, its inclusion as part of the ammunition formulation may act as an aversive agent.

Abstract:
The present disclosure is directed to significantly improving the adiabatic shear banding susceptibility of pure refractory metals as well as overcoming the physical dimension limitations when making kinetic energy penetrators. These improvements may be achieved by arranging interlayers between plasticly deformed refractory metal material layers. Disclosed herein are methods of making material for kinetic energy penetrator applications, the methods comprising: severely plasticly deforming a refractory metal material until the grain size of the refractory metal material is within one of ultrafine grain and nanocrystalline regimes; arranging an interlayer material adjacent the refractory metal material; and diffusion bonding the interlayer material to the refractory metal material.
Abstract:
A mechanically adaptable projectile includes, in one example embodiment, a projectile body, the body including structure adapted to secure thereto one of multiple projectile components, and multiple projectile components each sized to be releasably secured to the projectile body, each of the multiple projectile components structurally dissimilar from all others of the multiple projectile components.
Abstract:
A dissolvable glass projectile for a firearm is molded from dissolvable glass for the ammunitions and firearms industry. The dissolvable glass projectile may be molded into different sizes or geometry based on firearm and user preference. A mixture of chemicals components are heated and melted and then poured into a mold and is allowed to cool to a solid that can be handled.
Abstract:
Techniques and devices are disclosed for a nose insert and a projectile that include a polymer nose element and a metal tip. The polymer nose element includes a tapered head portion and a first shank portion attached to the tapered head portion. The tapered head portion includes a cavity disposed therein. The first shank portion includes a first diameter smaller than a width of the tapered head portion adjacent to the first shank portion. The metal tip disposed in the tapered head portion of the polymer nose element and includes a tapered end and a second shank portion attached to the tapered end. The second shank portion having a second diameter smaller than a width of the tapered end adjacent to the second shank portion. The second shank portion being received in the cavity within the tapered head portion of the polymer nose element.
Abstract:
Systems to measure muzzle exit conditions of for ammunition improve fire control solutions and reduce shot-to-shot dispersion in both conventional and air-burst programmable ammunition. A first system measures muzzle velocity and, when firing “post-shot” programmable ammunition, the system calculates a unique time-of-flight optimized for the actual muzzle velocity and transmits the time to detonate signal by using either optically or radio-frequency signals that represent an optimized time of burst to a projectile. A second system measures muzzle velocity coupled to a ballistic calculator and, when used with ammunition having ferrous characteristics, the force is applied to exiting ammunition to slow or increase the muzzle velocity to a consistent, standardized target velocity. The systems are separately or in combination incorporated into kits that readily improve the performance of weapon systems.
Abstract:
A dehydrated, pulp-based projectile is described. The projectile is pulp material that is molded and dehydrated into a projectile shape to form the dehydrated, pulp-based projectile. In operation, the pulp-based projectile can be positioned within the bullet chamber (e.g., gun clip) of a toy gun and then rehydrated. For example, the toy gun or bullet chamber can be dipped in water, which would cause the projectile to absorb the water and soften. An advantage to being pulp based is that the projectile is more solid than foam and, as such, generally shoots straighter and further than foam However, when rehydrated, the projectile has the propensity to stick to its target as it becomes pliable and sticky through rehydration.
Abstract:
A method for the manufacture of a projectile for small-bore weapons ammunition comprising the steps of producing a compact from a mixture of a heavy metal powder and a light metal powder at room temperature, and without further treatment of the compact, introducing the compact into a metal jacket, including pressing the compact into the jacket with a pressure sufficient to ensure substantially complete filling of a selected portion of the jacket by the compact. The compacts fill less that the entire volume of the jacket, leaving a portion of the jacket void of the compact. Prior to the pressing of the compact into the jacket, a disc having an outer diameter substantially equal to the internal diameter of said jacket adjacent the open end thereof is introduced into the jacket. Thereafter, that portion of the jacket adjacent its open end is infolded toward the longitudinal centerline of the jacket to at least substantially close the open end of the jacket.A unique projectile and a round of ammunition formed with the projectile are disclosed.
