摘要：
In order to obtain the aging rule of solid propellant better by EMI (Electro-mechanical impedance), and verify its scientific, reliability and validity from its physical characteristics, the parameters of electro-mechanical impedance proper ties and dynamic mechanical properties were correlated by theoretical derivation and analysis method. EMI and dynamic thermomechanical analysis (DMA) tests were carried out on HTPB propellant specimens with thermal aging, and the results were verified by the analysis. The results show that the electrical properties and dynamic mechanical properties of piezoelectric impedance can be related by the relationship between dynamic modulus and admittance, and the relationship between voltage-current lag angle and mechanical loss angle. The temperature spectrum peak value of loss factor tanδ of HTPB propellant varies with aging time at different testing frequencies, and the peak value decreases with the prolongation of thermal aging time. The tangent value of voltage and current lag angle tanβ can well reflect the aging of HTPB propellant. The tangent value of lag angle tanβ at resonance frequency decreases with the prolongation of thermal aging time, and it has obvious linear relationship with the peak value of loss factor tanδ. © 2019, Editorial Department of Journal of Propulsion Technology.
