Abstract

Understanding the rheological behavior of melt-cast explosives is critical for manufacturing melt-cast explosive charges. The research presented herein systematically investigates the rheological behavior of 2,4-dinitroanisole/tetramethylenetetranitra-mine (DNAN/HMX) melt-cast explosive suspensions. The rheological characteristics were measured using a Haake Mars III rheometer. In general, the DNAN/HMX melt-cast explosive suspensions underwent shear-thinning (pseudoplastic) and were strongly affected by solid content, particle size (unimodal distribution), particle gradation (bimodal or multimodal distribution), particle morphology, temperature, and chemical additives. The subsequent measurements and analysis provide important contextual information for designing formulations of DNAN/HMX melt-cast explosives.
