Metal binders for insensitive munitions

An explosive composition, an insensitive munition with a metal eutectic binder, and a method include using a metal eutectic binder with metal coated explosive particles. The metal eutectic binder concept represents novel melt-cast solid mixtures having explosives such as RDX (cyclonite) or HMX (octogen) distributed in an alloy including, for example, eutectic bismuth (Bi)/tin (Sn). Eutectic alloys are particularly considered to provide a melting point of the mixture below the exothermic point of the explosive so that vented munitions disarm by melting without exploding in the event of fire or other elevated heating. Particularly novel is the pre-coating of crystals of explosive (RDX/HMX) with a metal to promote wetting and bonding during melt fabrication of the final mixture. Copper, aluminum, and other metals are considered for use as coating.

Consumable weight components for flares and related flares

Flares with consumable weights connected to a forward end of the grain of the flare are disclosed. Also disclosed are consumable weight components for flares. The consumable weight components include a metal material within a matrix. Also disclosed are methods for fabricating a flare and methods for using a flare. Use of the consumable weights in the flares may reduce the amount of debris falling to ground.

Pyrophoric foam materials and methods of making the same

An in-situ process for synthesizing highly pyrophoric foam materials using metal and carbon precursors wherein the precursors serve as foaming and activating agents to disperse and lock nano-sized metal particles within a rigid porous carbon matrix. The resulting carbon matrix is also pyrophoric.
