Ultrasound Characterization of Plastic Bonded Explosives With Varied Binder Content and Density

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Advanced explosive formulations and methods of production require rapid characterization for both processes and materials. Here, we present results for ultrasound characterization of a plastic bonded explosive (PBX) formulation as a function of binder weight percent and pressing density using through‐transmission sound speed measurements.

Hydroxyl‐Terminated Polybutadiene‐Based Molding Powders as an Alternative Route for Manufacturing Pressed Polymer‐Bonded Explosives

Propellants, Explosives, Pyrotechnics, EarlyView.
This study presents an alternative method to manufacture polymer‐bonded explosives by partially curing an HTPB‐based molding powder prior to compaction. The study shows that the length of partial cure time before compaction directly influenced the geometric fidelity, homogeneity, compressive strength, density, and internal microstructure.

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers

River Research and Applications, EarlyView.
ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.
