Flexible Case-Grain Interactions in Ballistic Weapon Systems. Part I. Recovery of Strain Induced Damage in ANB-3066 Propellant. Part II. Viscoelastic Characterization of a Nonlinear Glass/Epoxy Composite Including the Effects of Damage.
Abstract
In part one, experimental evaluations of previous strain and recovery histories were conducted to determine their influences upon subsequent mechanical property characterizations of solid propellant grains. The purpose of the tests was to determine the effects of motor pressurization and thermal strains. Based on the experimental data contained in this report it is recommended that large propellant blocks from the dissected motor be stored stress-free at room temperature for a period of at least one month. In part two isothermal creep and recovery tests were conducted on an epoxy resin and a glass fiber-reinforced composite made from the same bulk resin. Both the epoxy and glass/epoxy were found to be thermorheologically complex materials with a creep compliance which may be represented by a power law in time.
