Abstract
Official abstract text for this publication.
A shaped charge liner comprises a powder, and the powder comprises a blend of particles. The particles comprise a core material, a first reactant material in intimate contact with the core material, and a second reactant material in intimate contact with the first reactant, where the core material has a density greater than 10 grams per cubic centimeter (g/cc).
First claim
Opening claim text (preview).
What is claimed is: 1. A shaped charge liner material for use in a shaped charge liner comprising: a powder comprising a core material, a first reactant material in intimate contact with the core material, and a second reactant material in intimate contact with the first reactant; wherein the core material comprises a density greater than 10 grams per cubic centimeter (g/cc); and wherein the first reactant material is reactive with the second reactive material. 2. The shaped charge liner material of claim 1 , wherein the core material comprises tungsten, tantalum, lead, gold, depleted uranium, or any combination thereof. 3. The shaped charge liner material of claim 1 , wherein the reactant materials comprise one of nickel paired with aluminum, tantalum paired with iron oxide, tantalum paired with copper oxide, and tantalum paired with tungsten dioxide. 4. The shaped charge liner material of claim 1 , wherein the diameter of the particles is less than 500 microns. 5. The shaped charge liner material of claim 1 , wherein the reactant materials comprise one of a thermite mixture and intermetallic reactants. 6. The shaped charge liner material of claim 5 , wherein the reactant materials comprise a stoichiometric mix of the first reactant material and the second reactant material. 7. The shaped charge liner material of claim 1 , wherein the first reactant material comprises a metal, and wherein the second reactant material comprises a metal oxide. 8. The shaped charge liner material of claim 1 , wherein the first reactant material comprises a metal oxide, and wherein the second reactant material comprises a metal. 9. The shaped charge liner material of claim 1 , wherein the first reactant material in intimate contact with the core material forms an intermediate shell of the powder, and wherein the second reactant material in intimate contact with the first reactant material forms an outer shell of the powder.
