Explosive device comprising an explosive material having controlled explosive properties
| DWPI Title: Explosive device comprises explosive material deposited on substrate surface, where porosity and density of explosive material deposited on surface of substrate is function of surface energy corresponding to substrate |
| Abstract: An explosive device is described herein, wherein the explosive device includes a substrate that has a surface, wherein surface energy of a portion of the surface of the substrate has been modified in a vacuum chamber from a first surface energy to a second surface energy. The explosive device additionally includes explosive material that has been deposited on the surface of the substrate in the vacuum chamber by way of physical vapor deposition (PVD), wherein the explosive material is deposited on the portion of the surface of the substrate subsequent to the surface energy of the portion of the surface of the substrate being modified from the first surface energy to the second surface energy. |
| Use: Explosive device. |
| Advantage: The explosive device improves safety compared to conventional initiators through the elimination of booster charges and primary high explosives, and allows for an explosive property to be finely controlled at any point on the surface of the substrate, and thus allows for an explosive device to be manufactured that has a controlled detonation velocity and/or detonation wave shape. |
| Novelty: Explosive device comprises a substrate having a surface, and an explosive material that is deposited on the surface of the substrate, where porosity and density of the explosive material varies across the surface of the substrate. The porosity and the density of the explosive material deposited on the surface of the substrate is a function of a surface energy corresponding to the substrate. |
