Binder-Filler Interaction in Energetic Polymers

Abstract

The objective of this study was to measure the kinetics of the dewetting process in a variety of filled energetic polymers being studied as candidates for improved solid rocket and gun propellants in the Office of Naval Research ONR Power Program. By studying the dewetting process in detail, correlations between surface energetics and dewetting behavior would be obtained. Specific questions addressed in this document are: 1) What is the relation, if any, between the particle size of RDX and the voids created by dewetting? 2) Does the number density of voids caused by strain vary with solids loading in the same binder? 3) What is the influence of plasticizers on the size and number density of voids? 4) What is the relative number density of voids in compositions that fracture at different strains? The size? and 5) What do the growth curves of voids look like as functions of strain? By combining Small Angle X-Ray Scattering (SAXS) and ultrasonic wave scattering (UWS) data with existing theories of scattering, partial answers to these questions can be derived.
