Study on the correlation between characteristic peaks of infrared absorption spectra and maximum elongation of HTPB propellant
In order to explore the correlation between the characteristic peaks of infrared absorption spectrum and the maximum elongation of HTPB propellant, the tensile test and Fourier infrared spectrum test of HTPB propellant after accelerated aging at 50 centigrade,60 centigrade and 70 centigrade were carried out. S-G smoothing filtering method and derivative spectrum method were used to process the infrared spectrum data, and the correlation between the infrared spectrum data and the maximum elongation was analyzed. The results show that the characteristic peak wave number of infrared absorption spectrum is highly related to the maximum elongation, and the fitting formula between the characteristic peak of infrared absorption spectrum and the maximum elongation is established at the wave number 1785cm-l; It was found that the maximum elongation of HTPB propellant decreases first in the aging process, then after a plateau period or rising period, and finally maintains a downward trend.
