초록

ABSTRACT : The aging characteristics of NEPE propellant is studied by HPLC analysis, cube crack test, swelling, and mechanical property test. The depletion of mixed stabilizer NMAI2-NDPA is analysed by Berthelot's law. The stabilizer NMA was completely comsumed after 16 weeks at $70{\circ}$ and after 6 weeks at $80{\circ}$ and the cracks developed in the sample. The aging trend of the propellant was shown hardening phenomena in the range of 20-$60{\circ}$ due to evaporation of energetic plasticizers.
