Abstract
Official abstract text for this publication.
The invention provides mechanically activated metal fuels for energetic material applications. An exemplary embodiment involves mechanically treating micrometer-sized particles of at least one metal with particles of at least one fluorocarbon to form composite particles containing the at least one metal and the at least one fluorocarbon.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for making mechanically activated metal fuels for energetic material applications, said method comprising: mechanically treating micrometer-sized particles of at least one metal with particles of at least one fluorocarbon to form composite particles containing the at least one metal and the at least one fluorocarbon in unreacted form, wherein the composite particles contain the at least one metal in a realitve amount of at least about 70 wt. % and wherein the composite particles contain the at least one fluorocarbon physically encased within particles of the at least one metal. 2. The method of claim 1 wherein the at least one fluorocarbon is a high fluorine content material devoid of oxygen. 3. The method of claim 1 wherein the at least one fluorocarbon is selected from the group consisting of polytetrafluoroethylene, poly(carbon monofluoride), 1-chloro-1,2,2-trifluoroethene, terpolymers based on tetrafluoroethylene, hexafluoropropylene and vinylidene fluoride, and combinations thereof. 4. The method of claim 1 wherein the at least one metal is selected from the group consisting of aluminum, boron, magnesium, silicon, lithium, and combinations or alloys thereof. 5. The method of claim 1 wherein said mechanical treatment comprises repeated plastic deformation of a mixture containing the micrometer sized particles of the at least one metal and particles of the at least one fluorocarbon. 6. The method of claim 1 wherein said mechanical treatment comprises milling. 7. The method of claim 6 wherein said milling comprises high energy milling. 8. The method of claim 6 wherein said milling comprises low energy milling. 9. The method of claim 1 wherein said mechanical treatment creates energy storing lattice defects within the composite particles. 10. The method of claim 1 wherein the composite particles contain the at least one fluorocarbon in a relative amount of up to about 30 wt. %.
