This paper reviews the main factors affecting the mechanical properties of GAP-based binders, such as molecular weight and functionality, and discusses some possible strategies on how it could be improved. The equation of Carother is used for the theoretical consideration of the functionality of the GAP prepolymer.englycidyl azide polymerGAPenergetic binderpropellant bindersmechanical propertiesjournal article
