A pressable explosive composition is provided. The composition includes at least 40 weight percent of substantially uncoated fuel particles, a nitramine mechanically blended with the substantially uncoated fuel particles, and a binder coating the nitramine. The binder constitutes about 1 to about 6 weight percent of the pressable explosive composition. Also provided are a pressed thermobaric explosive, weapons containing the pressed thermobaric explosive, and methods for making the composition and thermobaric explosive.

What is claimed is: 1. A method for making an explosive composition, comprising: coating a nitramine with a binder for forming a coated nitramine; and mechanically mixing the coated nitramine with substantially uncoated fuel particles under substantially dry, substantially solvent-free conditions partially encapsulating said substantially uncoated fuel particles with said binder of said coated nitramine for providing a pressable explosive composition comprising greater than 40 weight percent of substantially uncoated non-encapsulated fuel particles, and the coated nitramine, then pressing said composition in an apparatus, said apparatus comprising two capture members comprising nylon filled with molybdenum disulfide. 2. The method according to claim 1, wherein the coated nitramine constitutes about 1 to about 6 weight percent of the pressable explosive composition. 3. The method according to claim 1, wherein the substantially uncoated fuel particles are selected from at least one of the group consisting of aluminum, magnesium, and magnalium. 4. The method according to claim 1, wherein the substantially non-encapsulated uncoated fuel particles constitute about 50 to about 70 weight percent of the pressable explosive composition. 5. The method according to claim 1, wherein the substantially uncoated non-encapsulated fuel particles constitute about 60 to about 70 weight percent of the pressable explosive composition. 6. The method according to claim 1, wherein the substantially uncoated non-encapsulated fuel particles have an average particle diameter of about 1 micron to about 5 microns. 7. The method according to claim 1, wherein the nitramine comprises a member selected from HMX and RDX. 8. The method according to claim 1, further comprising an ionic salt oxidizer coated with the binder. 9. The method according to claim 8, wherein the substantially uncoated non-encapsulated fuel particles, the nitramine, and the ionic salt oxidizer collectively constitute from about 92 weight percent to about 99 weight percent of the pressable explosive composition. 10. The method according to claim 1, further comprising pressing the pressable explosive composition into a shaped object. 11. A method for pressing a pressable explosive composition into a pressed thermobaric explosive, comprising: providing a mold apparatus comprising a die having an inner surface defining side walls of a cavity, a first ram and a second ram being movable relative to one another for defining opposite walls of the cavity, respectively, and a first capture member and a second capture member being snugly fit in the die for producing a scraping action as the first capture member and the second capture member are being non-integrated with the first ram and the second ram; situating a sample of the pressable explosive composition in the cavity of the mold apparatus; positioning the first capture member between the first ram and the sample, and positioning the second capture member between the second ram and the sample so that the first capture member and the second capture member are separate from the first ram and the second ram; and moving the first ram toward the second ram to press the pressable explosive composition into the pressed thermobaric explosive, wherein the pressable explosive composition comprises greater than 40 weight percent of substantially uncoated non-encapsulated fuel particles and a coated nitramine, wherein each of the first capture member and the second capture member is comprised of nylon filled with molybdenum disulfide. 12. The method according to claim 11, wherein the side walls of the cavity are coated with grease. 13. The method according to claim 11, wherein a clearance exists between outer surfaces of the first ram and the second ram and the side walls, and wherein the first capture member and the second capture member have peripheries in continuous contact with the side walls, providing a scraping action that prevents fine fuel particles from jamming the first ram and the second ram. 14. The method according to claim 11, wherein each of the first capture member and the second capture member includes a diameter in a range of 0 to 0.0005 inches, which is larger than an inner diameter of said die. 15. The method according to claim 11, wherein each of the first capture member and the second capture member is comprised of nylon filled with 15 percent molybdenum disulfide.
