Sažetak
Dynamic mechanical analysis (DMA) is a powerful technique for determination of mechanical properties of rocket propellants. This technique enables determination of the storage and loss modulus of a propellant against time, temperature or frequency of an oscillation load, while the temperature of the sample in a specified atmosphere is programmed. However, like many other thermal methods DMA gives results that may depend greatly on the conditions used during the experiment. Thus, it is very important to use such experimental parameters that will minimise the error caused by the dynamic nature of the experiment, sample dimensions, etc. In this work we have studied influence of heating rate, frequency, and length to thickness ratio on results of dynamic mechanical analysis. The results obtained have shown that the experimental parameters may have significant influence on values of the viscoelastic function for double base propellant.
