摘要
Solid rocket propellants have been used for many decades, virtually beginning with the advent of rocketry. They are typically highly filled polymers with filler loadings of about seventy or greater volume percent. High filler loadings serve to optimize the energy content of the propellant. To incorporate more performance into a propellant, one can include an energetic plasticizer. Certain formulations of highly plasticized, highly filled, crosslinked and semicrystalline solid rocket propellants have been observed to have uncommonly high strain-to-failure properties in uniaxial tension. With this increase in ballistic performance comes the unexpected advantage of good mechanical performance. The origin of this behavior has been unknown, although one may speculate that plasticizer effects on the semicrystalline binder, binder-filler interactions, and crystallinity are important. Since handling explosives is too dangerous, this study uses a model system which seeks to replicate the real material in every way, with the exception of substitutions for the two explosive components - nitroglycerine and ammonium perchlorate. The objective of this investigation is to determine quantitatively the origin of the high strain-to-failure behavior in these formulations.
