Chemical Structural Aging Effects.

Abstract

This program is determining the individual chemical rate processes that govern the aging of ANB-3066 propellant, and it is attempting to establish the effect of chemical (compositional) changes upon the system's mechanical response to enable better utilization of accelerated surveillance test data. Chemical changes, as they occur in the propellant under the influence of time, temperature and stress are determined by reflectance infrared techniques, measurement of sol content and crosslink density, off-gas analysis, and analysis (GPC/infrared) of sol extracts. The system's changes in chemical composition, as evidenced by these measurements, are then related to corresponding changes in mechanical response as determined by uniaxial tensile measurements and measurement of creep compliance and tear propagation. The report outlines the experimental matrix to be followed, and it quotes initial data obtained with ANB-3066 propellant and an analog propellant containing KC1 in substitution of ammonium perchlorate.
