This paper presents the procedure of uniaxial mechanical characterization of composite solid rocket propellant based on hydroxy-terminated polybutadiene (HTPB), whose mechanical properties strongly depend on temperature, strain rate, natural aging and accumulated damage. A method of processing data is presented in order to determine time-temperature shift factor and master curves for tensile strength, ultimate strain and relaxation modulus, depending on reduced time. Functional dependences of these features represent an input for structural analysis of a rocket motor propellant grain. The effects of natural aging on the mechanical properties are also considered.

Proper Operation

Proper operation of rocket motor depends significantly on thermo-mechanical properties of propellant used. For this reason it is important that characteristics of a particular propellant versus the time and temperature pass a thorough investigation to assess its operation at different conditions. The paper illustrates investigations of ageing process influencing thermo-mechanical properties of homogeneous rocket propellant. A selected type of rocket propellant was subjected to accelerated ageing in conditions specified in AOP-48 document to establish in the next step its thermal and mechanical characteristics (between all the temperature of glass transition and decomposition). The ageing of propelling explosives causes the reduction of stabiliser content deciding about thermo-mechanical properties of propellant and for that the percentage of effective stabiliser and its loss were identified by liquid chromatography HPLC. Thermal properties were investigated by differential scanning calorimetry. Thermal analyses were carried out according to STANAG 4515. Mechanical characteristics were tested by dynamic mechanical analysis (DMA) in line with STANAG 4540.
