The Effect of Aging on the Properties of Composition B

Abstract

Selected safety and characterization tests were conducted on Composition B from a 31 year old lot in order to evaluate the effect on aging on the properties of the explosive. The results of the tests are compared to those for Composition B from recent lots. The tests included impact sensitivity, friction sensitivity, electrostatic sensitivity, explosion temperature, differential thermal analysis, thermogravimetric analysis, autoignition temperature, large scale gap test, growth characteristics, and detonation velocity. The data showed that no significant changes have occurred to the explosive since it was manufactured in 1952. The only change noted was that the aged Composition B exhibited a slightly greater irreversible volume change than the Composition B from a recently manufactured lot.
