Influence of Bonding Agents on Mechanical Properties of Nitrate Plasticized BAMO-THF Propellants

The influence of two types of bonding agents on mechanical properties of nitrate plasticized BAMO-THF propellants was studied by using uniaxial tension test.The section micromorphology of nitrate plasticized BAMO-THF propellants without bonding agent and with neutral polymer bonding agent(NPBA) was observed by scanning electron microscopy.The results show that comparing to polar bonding agents such as MAPO,T-313 and HX-752,NPBA can obviously increase the maximum tensile strength and maximum elongation at break of nitrate plasticized BAMO-THF propellants.The both maximum tensile strength and maximum elongation at break of propellants approach to maximum value when mass fraction of 4# NPBA is 0.15%.
