| Abstract: | In situ observations of scanning electron microscopy(SEM) during uniaxial tensile process and swelling ratio measurements were applied to study the influences of neutral polymeric bonding agents(NPBA)on the interfacial interactions between the polymer matrix and organic nitramine fillers in the solid propellant. The results show that NPBA is able to form a high modulus interphase around the HMX filler particles, which may effectively improve the affinity of the two phases and successively solve the problems of "dewetting". It is a promising way for improving the mechanical properties of the propellant. |
