| Abstract: | The dynamic viscoelastic properties of the nitramine and nitroguanidine propellants in the aging process were studied in this work. The variation of the dynamic storage modulus and the loss tanget with the aging time was discussed,and the relationship between loss tanget and the impact fracture toughness was also theoretically analysed. The critical aging time of these two kinds of propellants was given and the results presented in this paper could be taken as a guideline for the preparation and the use of the propellants. |
