Novel evaluation enhancement role of poly (1-(3-nitrophenyl)-1H-1,2,3-triazol-4-yl) acrylate materials for propellant composite formulation

Abstract

The performance of solid propellants is often tailored by incorporating energetic materials such as novel oxidizers, energetic binders and ballistic modifiers. Metal oxide nanoparticles are known for their persuasivenature to modify burning rate ofammonium perchlorate based composite propellants. In the present work, nano iron oxide and poly (1-(3-nitrophenyl)-1H-1,2,3-triazol-4-yl) acrylate are incorporated in the composite propellant formulation by partly replacing coarse ammonium perchorate (AP) as well as hydroxy terminatined polybutadiene (HTPB), respectively, and different properties were evaluated. The mechanical properties data revealed that on increasing the percentage of polymer in the composition by partly replacing HTPB, there is an increase in tensile strength while decreasing elongation percentage. Thedata of ballistic properties revealed that on incorporation of nano iron oxide in the composition enhances the burning rate while on partial replacement of HTPB with polymer there is a decrease in burning rate from 11.95 mm s−1 to 8.75 mm s−1, respectively was observed.
