Thermoplastic Elastomers as LOVA Binders

Abstract

The prediction of the mechanical behavior of particulate composite under thermal of mechanical stresses is of great importance in the effective design of solid propellants. The presence of voids due to the debonding of oxidizer particles results in significant changes in burn rate which cannot be tolerated. Prediction of the stress strain and volumetric behavior of particulate composites over the range of strain where debonding occurs would allow design of proper processing techniques to avoid this problem. The method presented appears to have the potential to accurately predict the s strain and dilatation strain curves for systems filled with spherical particles subjected to uniaxial tension and superimposed pressure. Keywords: Liquid crystals, Propenes, Synthesis(chemistry), Thermoplastics, Elastomers, Copolymers, Birefringence, Viscosity, Crack propagation, Debonding, Elasticity, Voids.
