  • Patent number: 8317978
    Abstract: A method of fabricating a non-brittle, carbon nanopaper from single wall, multiwall, and combination thereof, from carbon nanotubes, using a vacuum deposition, high temperature annealing, and polystyrene polymer rinse process; which nanopaper can be nitrided by either a plasma-enhanced chemical vapor deposition (PECVD) process, or an by an electrochemical method, to obtain a useful chemically functionalized substrate, a substrate containing metastable N4, N8, and longer chain polymeric nitrogen clusters. Such nitrided carbon nanopaper can be used to enhance the ballistic performance of gun propellants, while reducing gun barrel wear and erosion thereof.

  • Patent number: 7862668
    Abstract: A gun propellant formulation comprising: a nitrocellulose component comprising from about sixty-five percent (65.0%) to about ninety-five (95.0%) of the gun propellant by weight, having a nitrogen proportion of substantially twelve and six-tenths percent (12.6%) nitrogen; an energetic plasticizer component comprising from about 5.0 percent (5.0%) to about 35 percent (35.0%) of the gun propellant by weight, and comprising N-Butyl-2Nitratoethyl Nitramine (BuNena); a burning rate moderator and stabilizer component comprising from about one-half of one percent (0.5%) to about five percent (5.0%) of the gun propellant by weight, and comprising Sym-Diethyl Diphenyl Urea, N,N?-Diethyl Carbanilide (Ethyl Centralite, Centralite I); and a stabilizer component comprising about one-half of one percent (0.5%) to about five percent (5.0) of the gun propellant by weight, and comprising Acetyl triethyl citrate (ATEC).

  • Patent number: 6997996
    Abstract: A high energy propellant, comprising an oxetane thermoplastic elastomer energetic binder admixed with a high energy explosive filler. The oxetane thermoplastic elastomer energetic binder preferably comprises from about five percent to about thirty percent by weight and the high energy explosive filler comprises from about seventy percent to about ninety-five percent by weight of the composition. A preferred propellant further includes an explosive plasticizer, preferably in an amount of about four percent to about seven percent of the plasticizer by weight of the propellant. The preferred filler is selected from the group consisting of CL-20, TNAZ, RDX and mixtures thereof. The preferred plasticizer is selected from the group consisting of TNAZ, BTTN, TMETN, TEGDN, BDNPA/F, methyl NENA, ethyl NENA and mixtures thereof.

  • Patent number: 6607618
    Abstract: The present invention shows a munitions propellant. The propellant has a nitrocellulose component is about fifty-two percent (52.0%) of the propellant. This is either a nitrocellulose having twelve and six-tenths percent (12.6%) nitrogen, or a combination of a nitrocellulose having twelve and six-tenths percent (12.6%) nitrogen and a nitrocellulose having thirteen and thirty-five one hundredths percent (13.35%) nitrogen, and in which the average nitrogen proportion is thirteen and five one-hundredths percent (13.05%). The propellant also has a nitroester-based plasticizer and a non-nitroester-based plasticizer. The nitroester-based plasticizer comprises about thirty-four percent (34.0%) of the propellant by weight, and comprises diethylene glycol dinitrate (DEGDN). The non-nitroester-based plastizier comprises from about three percent (3.0%) to about four percent (4.0%) by weight and comprises di-normal propyl adipate (DNPA). In addition, about seven percent (7.

  • Patent number: 6524706
    Abstract: A main energetic ingredient filler useful for propellant-based munitions, comprising filler particles having a fine particle size of less than about 10 micrometers diameter and a thin coating of graphite on the filler particles in an amount such that the weight of the graphite is less than about two percent of the weight of the filler particles. Preferred filler particles have a fine particle size of less than about ten micrometers diameter, and most preferred are fillers with a particle size having an average particle diameter ranging from about two to about eight micrometers. The preferred filler is selected from the group consisting of CL-20, TNAZ, NQ, RDX, HMX and mixtures thereof. Most preferred is a filler of CL-20 ground to an average particle diameter of about five to ten micrometers. The preferred amount of graphite comprises about one percent by weight of the filler particles. The filler may be formed into a propellant including a binder and a plasticizer.

  • Patent number: 5567912
    Abstract: The invention is an insensitive energetic composition that is an explosive and the related articles and systems. The composition has HMX or RDX as an energetic filler, a nonenergetic binder and an energetic plasticizer. The plasticizer is a nitrato-nitramine or a liquid nitrate ester. This provides a matrix with a glass transition temperature below minus 45 degrees Centigrade. In another variation, the composition can also include aluminum powder. Generally, the materials have particularly strong blast effects.
