| description | Herein, we present a thermo-mechanical analyzer (TMA) and dynamic mechanical analyzer (DMA) of composite multi-layered gun propellant, focusing on thermal expansion coefficients and dynamic thermomechanical properties. The linear thermal expansion coefficient of the prepared energetic material is determined as approx. 0.1800 × 10−4 - 0.2081 × 10−4 K−1. According to DMA test and dynamic thermomechanical properties, the glass transition temperature is also obtained. The tested value is within the range of 223.01–223.50 K, which indicates the lower limit of the energetic material. However, DMA tests reveal temperature changes, which occur due to thermal expansion. Moreover, the geometrical factor decreases with increasing temperature. Therefore, thermal expansion significantly affects the storage modulus and loss modulus. Additionally, the thermal expansion coefficient can be used to modify the storage and loss modulus. The results show that the proposed method provides effective and reliable modified results. |
