Viscoelastic Properties of Solid Propellants and Propellant Binders

Abstract

Studies supplementary to the determination of the dynamic shear modulus are reported. The effects of specimen geometry and the magnitude of shear strain on the dynamic modulus of polyurethane propellant AEBA-10 were studied. A method was worked out to correct measurements to the same level of shear strain to allow a direct comparison under all experimental conditions. An evaluation of the differential Lissajous method for determining small phase angles has shown that, at frequencies as low as 0.05 cps, a phase angle of the order of a few thousandths of a radian can be measured with good precision. Factors that influence the reproducibility of data obtained with the dynamic compressibility apparatus were investigated.
