摘要

The development of new propellant binder systems requires the thermodynamic calculation of physico-chemical data as well as the adaption of the mechanical properties in order to achieve a reliable innerballistic profile of the resulting propellant.Therefore,this study focuses on the mechanical properties of a binder system comprising GAP,NC as well as the energetic plasticizer DNDA and the curing agent Desmodur N100.By applying statistical methods,the mechanical properties of the binder can be predicted as a function of its composition.A macroscopic analysis of the interrelations between the E-modulus,the ultimate tensile strength as well as the elongation at break and the specific deformation energy lead to the creation of failure master curves,which can be used as a rule of thumb criterion for the formulation of propellant binders.
