First claim
Opening claim text (preview).
What is claimed is: 1. An explosive cord, comprising: a tubing, comprising polymeric material, the tubing comprising an inner surface and an outer surface; a reactive material comprising hexanitrostilbene coupled circumferentially to the inner surface of the tubing; and a hollow core through a center of the explosive cord, the hollow core being defined by the reactive material. 2. The explosive cord of claim 1 , further comprising an outer layer coupled circumferentially to the outer surface of the tubing. 3. The explosive cord of claim 2 , wherein the outer layer comprises a metal material. 4. The explosive cord of claim 3 , wherein the outer layer comprises steel. 5. The explosive cord of claim 1 , wherein the tubing comprises a fluoropolymer. 6. The explosive cord of claim 5 , wherein the tubing comprises poly ethylene chlorotrifluoroethylene. 7. The explosive cord of claim 1 , wherein the reactive material further comprises aluminum metal. 8. The explosive cord of claim 7 , wherein the reactive material comprises between 70% and 100% by weight hexanitrostilbene.
