Abstract
A method of permanently affixing tungsten cube fragments to the fragmentation warhead in a convex Claymore mine having a plastic case and a housing. Pieces of predetermined sized structural film adhesive are positioned at temperature 60° F.±5° F., then pressed into the plastic case while pouring tungsten cubes into the case. The cubes are arranged into desired patterns all at temperature 70° F.±2° F. An interface plate and 5 lbs of weight are then placed atop thereof and all are heated in an oven at temperature 205° F.±5° F. for four hours for full cure of a desired product.
Claims9
Method of permanently affixing fragments (105) upon a fragmentation warhead in a convex Claymore matrix (106) having a plastic case and a housing, comprising the steps of:
- cutting out two (2) pieces of predetermined width and length from a structural film adhesive (104) at temperature 60° F.±5° F.;
- then,
- positioning and pressing said film adhesive pieces into the plastic case at temperature 70° F.±2° F.;
- then,
- pouring fragments into the case, at temperature 70° F.±2° F.;
- then,
- arranging said fragments into the desired pattern while in the case, at temperature 70° F.±2° F.;
- then,
- pressing the film adhesive pieces into the patterned fragments, at temperature 70° F.±2° F.;
- then,
- pressing a piece of sheet metal (103) into the film adhesive pieces, at temperature 70° F.±2° F.;
- then,
- placing an interface plate (102) and 5 lb of weight (101) onto the top of said sheet metal;
- then,
- placing all the above assembled items in an oven at temperatures of 205° F.±5° F., for four hours, for full cure of the said adhesive pieces in the said Claymore matrix;
- and,
- whereupon said fragments have therefore been permanently attached to said Claymore matrix exactly in a desired pattern, and without deforming or degrading of the Claymore matrix housing.
Method of permanently affixing tungsten cube fragments to a fragmentation warhead in a convex Claymore matrix having a plastic case and a housing, comprising the steps of:
- cutting out two (2) pieces of predetermined width and length of 0.060 WT (weight), AF 163-2M structural film adhesive, at temperature 60° F.±5° F.;
- then,
- positioning and pressing said film adhesive pieces into the plastic case at temperature 70° F.±2° F.;
- then,
- pouring tungsten cubes into the case;
- at temperature 70° F.±2° F.;
- then,
- arranging said cubes into the desired pattern while in the case, at temperature 70° F.±2° F.;
- then,
- pressing the film adhesive pieces into the patterned cubes, at temperature 70° F.±2° F.;
- then,
- pressing a piece of sheet metal into the film adhesive pieces, at temperature 70° F.±2° F.;
- then,
- placing an interface plate and 5 lb of weight onto the top of said sheet metal;
- then,
- placing all the above assembled items in an oven at temperatures of 205° F.±5° F., for four hours, for full cure of the said adhesive pieces in the said Claymore matrix;
- and,
- whereupon said tungsten cubes have therefore been permanently attached to said Claymore matrix exactly in a desired pattern, and without deforming or degrading of the Claymore matrix housing.
