Research Progress of Bonding Agents for Nitramine Composite Solid Propellants

Abstract

This review article summaries the method to improve mechanical properties of nitramine composite solid propellants. It concludes that the use of bonding agents is an economical, effective and convenient way to enhance the mechanical properties of propellants. The bonding mechanism and characteristics of bonding agents are analyzed. The review article presents the overview on the types and development of bonding agents for nitramine composite solid propellants. It is considered that the multi-functionalization of polymer bonding agents is a development direction of bonding agents. According to the surface characteristics of nitramine fillers and the structure characteristics of different binders, a universal bonding agent suitable for different binder-nitramine systems should be prepared through molecular design. Some suggestions are put forward for the design of universal bonding agents.
