ABSTRACT As a bonding material for the shell and propellant in combustion chamber of solid rocket motor, liner plays protective role engine. Only when is “semi‐solidified state” can charge quality be guaranteed, it easy to cause phenomenon unstable interface if loaded too early or late. Therefore, noncontact monitoring gradual solidification process from liquid state prevent problems significantly improve safety motors. In this paper, reflective terahertz time‐domain spectroscopy technology used monitor curing lining materials, extract refractive index spectra samples with different degrees, establish relationship between reaction time, compare loss factor obtained by rheometer correlation factor. The experimental results show that decreases gradually during process, coefficient higher than 0.9. With reaction, accurately reflect polyurethane materials. This study provides an effective means
