Studies on an Improved Plastic Bonded Explosive (PBX) for Shaped Charges
TL;DR: In this paper, the characteristics and performance evaluation of a pressed plastic bonded explosive (PBX) composition based on hexanitrohexaazaisowurtzitane (HNIW, CL-20) and polyurethane (PU) in comparison with PU-coated cyclotetramethylene tetranitramine (HMX) was reported.
Journal ArticleDOI

Michael D. Joseph,Suresh Kumar Jangid,Ravindra S. Satpute,Bhagwan G. Polke,Tribhuran Nath,S. N. Asthana,Alapati Subhananda Rao +6 more
TL;DR: In this article, the effect of incorporation of TATB on physical, thermal, and sensitivity behavior as well as initiation by small and high caliber shaped charges has been determined, and the incorporation of 10−20% TAB at the cost of RDX led to a remarkable increase in density (1.43→1.49"g"cm−3) and tensile strength (10→15"kg cm−2) compared to the control composition RDX/HTPB(85/15).
Journal Article
Synthesis, characterization and thermal behavior of hydrazinium nitroformate (HNF) and its new N-alkyl substituted derivatives
TL;DR: In this article, two new derivatives of hydrazinium nitroformate (HNF) viz., mono methyl hydrazine and dimethyl hydrazina hydrate have been synthesized and characterized by elemental, spectral and thermal analysis.
Journal Article
Alternate method for synthesis of 1,3,3-trinitroazetidine (TNAZ): Next generation melt castable high energy material
TL;DR: In this paper, the synthesis of 1,3,3-trinitroazetidine (TNAZ) from 2,2-dinitropropane-1, 3-diol precursor derived from nitromethane is described.
