The method includes the step of providing a first compressible material, providing an energetic material, and combining the first compressible material and the energetic material into a composite material. The composite material is supplied to a plurality of pairs of primary compression rollers and compressed into a single web. The single web can be extruded through an extruder in a final mixing step. ## Claims ### Claim 1 A method for producing a compressed composite material, comprising, providing a first compressible material; providing an energetic material; combining the first compressible material and the energetic material into a composite material; supplying the composite material to a pair of primary compression rollers; compressing the composite material through the pair of primary compression rollers into a web; combining and compressing the web through a pair of secondary compression rollers; providing an extruder; and extruding the web through the extruder as a mixed, compressed composite energetic material. ### Claim 2 (depends on 1) The method for producing a compressed composite energetic material of claim 1, wherein the energetic material is in a granular form. ### Claim 3 (depends on 1) The method for producing a compressed composite energetic material of claim 1, wherein the energetic material is cyclonite. ### Claim 4 (depends on 1) The method for producing a compressed composite energetic material of claim 1, wherein the energetic material is hexogen. ### Claim 5 (depends on 1) The method for producing a compressed composite energetic material of claim 1, wherein the energetic material comprises cyclotetramethylenetetranitramine. ### Claim 6 (depends on 1) The method for producing a compressed composite energetic material of claim 1, wherein the energetic material comprises trinitrotoluene. ### Claim 7 (depends on 1) The method for producing a compressed composite energetic material of claim 1, further comprising providing a second compressible material, combining the first and second compressible materials, and wherein the energetic material is combined with one of the first compressible material and the second compressible material. ### Claim 8 (depends on 1) The method for producing a compressed composite energetic material of claim 1, wherein the pair of primary compression rollers comprise two metal rollers having parallel rotational axes. ### Claim 9 (depends on 1) The method for producing a compressed composite energetic material of claim 1, wherein the pair of secondary compression rollers comprise two metal rollers having parallel rotational axes. ### Claim 10 A method for producing a compressed composite material, comprising, providing a first compressible material; providing an energetic material; combining the first compressible material and the energetic material into a composite material; supplying the composite material to a plurality of pairs of primary compression rollers; compressing the composite material through the plurality of pairs of primary compression rollers into a plurality of webs; combining and compressing the plurality of webs through a pair of secondary compression rollers into a single web; providing an extruder; and extruding the single web through the extruder as a mixed, compressed composite energetic material. ### Claim 11 (depends on 10) The method for producing a compressed composite energetic material of claim 10, wherein the energetic material is in a granular form. ### Claim 12 (depends on 10) The method for producing a compressed composite energetic material of claim 10, wherein the energetic material is cyclonite. ### Claim 13 (depends on 10) The method for producing a compressed composite energetic material of claim 10, wherein the energetic material is hexogen. ### Claim 14 (depends on 10) The method for producing a compressed composite energetic material of claim 10, wherein the energetic material comprises cyclotetramethylenetetranitramine. ### Claim 15 (depends on 10) The method for producing a compressed composite energetic material of claim 10, wherein the energetic material comprises trinitrotoluene. ### Claim 16 (depends on 10) The method for producing a compressed composite energetic material of claim 10, further comprising providing a second compressible material, combining the first and second compressible materials, and wherein the energetic material is combined with one of the first compressible material and the second compressible material. ### Claim 17 (depends on 10) The method for producing a compressed composite energetic material of claim 10, wherein the plurality of pairs of primary compression rollers comprise two metal rollers having parallel rotational axes. ### Claim 18 (depends on 10) The method for producing a compressed composite energetic material of claim 10, wherein the plurality of pairs of secondary compression rollers comprise two metal rollers having parallel rotational axes. ### Claim 19 (depends on 10) The method for producing a compressed composite energetic material of claim 10, wherein the extruder is a screw extruder. ### Claim 20 (depends on 10) The method for producing a compressed composite energetic material of claim 10, further comprising guide members.
