Resonant Acoustic Mixing Processing and Characterization
Abstract
Equipment is requested to establish resonant acoustic mixing (RAM) processing and characteriza-tion facilities at the University of Maryland (UMD), College Park, to support and extend the follow-ing research activities: (i ) theoretical and computational modeling of RAM for energetics (ONR),(ii ) additive manufacturing for meta-structure-assisted RAM of polymer-bonded explosive (PBX)simulants (ONR), (iii ) machine learning for energetic materials (ONR), and (iv ) RAM-enabledtwo-photon direct laser writing of 3D microelectronics for sensor swarms capable of structuralhealth monitoring in collaboration with the U.S. Army Research Laboratory (ARL). The proposedequipment will enable studies that establish and elucidate the underlying mechanisms relevantto a) pre-mix micro/mesoscale structural factors, b) multiscale RAM dynamics, c) post-mix mi-crostructure, and d) post-mix properties and performance. The results of these research activitieswill directly advance the current understanding of process-structure-performance relationships formaterials processed via acoustic mixing strategies, thereby establishing new foundational insightsuseful for predicting and, in turn, controlling the ultimate performance of mixed materials that arecritical to U.S. defense capabilities.The proposed equipment includes the following: (i ) Resodyn Acoustic Mixers LabRAM II Bench-Top Mixing System with Automatic Vacuum, and (ii ) Hitachi TM4000Plus Tabletop Microscopewith Tilt-Rotate Stage and Oxford AZtecOne Electron-Dispersive X-Ray Spectroscopy (EDS) Sys-tem. Along with existing acoustic and optical tools, the requested equipment will help create a setof unique and dedicated capabilities for RAM processing and characterization of mixed functionalmaterials (e.g., energetic and microelectronic materials). These combined experimental and com-putational capabilities, coupled with existing core facilities and additive manufacturing technologies,will form an unprecedented and unique capability to examine acoustic mixing. These capabilitieswill drive current program e -orts to understand the characteristics of mixed materials, particularlythose critical to energetic and microelectronic applications. The requested equipment will alsoserve as a versatile platform for on-site training of undergraduate and graduate students as well asengineers from local academic, industrial, and government facilities.
