THE RELATIONSHIP BETWEEN THE ENTHALPIC RELAXATION AND MECHANICAL RELAXATION FOR SOME ENERGETIC MATERIALS AT LOW TEMPERATURE

摘要

The relationships between the glass transition temperature T_g and the heating rate and the frequency were found by using DSC and DMA for some propellants respectively. The relationship of glass transition temperatures measured by the two methods was obtained, and the mechanical relaxation was correlated to the enthalpic relaxation.
