少烟NEPE推进剂的动态力学性能
Dynamic Mechanical Characteristics of the Low Smoke NEPE Propellant
摘要
Abstract
The viscoelastic characteristics of the low smoke NEPE propellant and the binder films were studied by the dynamic mechanical analyzer. The results indicated that the ￡' of the PET/N100 binder film, PET/N100/NG-TEGDN film and propellant are increased, the E" of the PET/N100 binder film reaches to the maximum, while the propellant is the minimum in the glassy state; E of the samples are decreased obviously in the vitrification transition region, the Tg of the samples are -82℃ , -73℃ and -65℃ respectively; a peak was appeared at -24℃ in E' and ￡" of the PET/N100 binder film in the rubbery state, while those of the other samples were decreased significantly, an obvious a relaxation peak was found at -3℃ and the a relaxation peaks of PET/N100/NG-TEGDN film and propellant were shifted to -24℃.关键词
