Reactive material compositions and projectiles containing same
View Patent ↗A reactive material that includes at least one of a fuel, an oxidizer, and a class 1.1 explosive and is formulated for use in a reactive material projectile. The reactive material is formulated to provide at least one of an overpressure of greater than approximately 9 pounds per square inch at a radial measurement of 12 inches from a point of impact on a target, a hole greater than approximately 2 square inches at an optimum penetration level in a target, and pressure, damage, and a flame when the reactive material bullet impacts a target. The fuel may be a metal, a fusible metal alloy, an organic fuel, or mixtures thereof. The oxidizer may be an inorganic oxidizer, sulfur, a fluoropolymer, or mixtures thereof. A reactive material projectile having the reactive material disposed therein is also disclosed.
1. A reactive material, consisting of:
a metal selected from the group consisting of magnesium, zirconium, aluminum, titanium, and hafnium;
cupric oxide; and
a copolymer of vinylidenefluoride-hexafluoropropylene.
2. The reactive material of claim 1 , wherein the cupric oxide comprises from approximately 10% by weight to approximately 81% by weight of the reactive material.
3. A reactive material projectile, comprising:
a case having a reactive material disposed therein, and a tip, wherein the reactive material consists of a metal selected from the group consisting of magnesium, zirconium, aluminum, titanium, and hafnium, from approximately 18% by weight to approximately 78% by weight cupric oxide, and a copolymer of vinylidenefluoride-hexafluoropropylene.
4. The reactive material projectile of claim 3 , wherein the reactive material is formulated to initiate upon impact of the reactive material projectile with a target.
5. A reactive material, consisting of:
a metal selected from the group consisting of magnesium, zirconium, aluminum, titanium, and hafnium;
from approximately 18% by weight to approximately 78% by weight cupric oxide; and a copolymer of vinylidenefluoride-hexafluoropropylene.
6. The reactive material of claim 5 , wherein the reactive material consists of magnesium, cupric oxide, and a copolymer of vinylidenefluoride-hexafluoropropylene.
7. The reactive material of claim 5 , wherein the reactive material consists of zirconium, cupric oxide, and a copolymer of vinylidenefluoride-hexafluoropropylene.
8. The reactive material of claim 5 , wherein the reactive material consists of aluminum, cupric oxide, and a copolymer of vinylidenefluoride-hexafluoropropylene.
9. The reactive material of claim 5 , wherein the reactive material consists of titanium, cupric oxide, and a copolymer of vinylidenefluoride-hexafluoropropylene.
10. The reactive material of claim 5 , wherein the reactive material consists of hafnium, cupric oxide, and a copolymer of vinylidenefluoride-hexafluoropropylene.
11. The reactive material of claim 5 , wherein the metal comprises from approximately 15% by weight to approximately 90% by weight of the reactive material.
12. The reactive material of claim 5 , wherein the metal comprises from approximately 10% by weight to approximately 90% by weight of the reactive material.
13. The reactive material of claim 5 , wherein the cupric oxide has a particle size ranging from approximately 20 nm to approximately 200 μm. wherein initiation of the reactive material occurs upon impact.
