Abstract:   (4398 Views)
Bonding agents are important components in solid propellants which affect processing, mechanical, ballistics, safety and aging properties of propellant. In this research, we have synthesized and characterized three types of new polymeric bonding agents by post functionalization of glycidyl azide polymers (GAP) via click chemistry. The interaction of new bonding agents with the surfaces of RDX particles have studied by IR spectroscopy that shown a 7/86 shift of nitro group absorption peak at 1593 cm-1 .Also , The mechanical properties of a typical HTPB base propellant with new polymeric bonding agent are considerably improved. The value of maximum tensile strength is increased from 0/53 MPa to 0/85 MPa and the value of maximum strain at break is increased by % 147 at 25 °C . As well as, the results of DSC trace show that the thermal stability of the polymer bonding agents is acceptable for using in a propellant formulation.
