  • Process for producing non-detonable training aid materials for detecting explosives
    Patent number: 9108890
    Abstract: A method for manufacturing training aid materials for detecting homemade explosives includes spreading an explosive powder on a porous surface, storing the surface in a container that facilitates sublimation of the explosive powder such that the explosive powder redeposits onto the surface and into the pores over a period of time, and removing the surface from the container after the period of time to yield training aid materials. An additional method includes preparing a dilute solution of an explosive reaction mixture, and depositing the dilute solution on a surface prior to formation of an explosive product by the explosive reaction mixture. The surface is stored in a contain that facilitates formation of the explosive product, and removed after a period of time and cleaned to remove unreacted precursors to yield training aid materials.
