This $200,000 National Science Foundation (NSF) Engineering grant (CFDA 47.041) supports fundamental research at Texas State University to investigate material-process-microstructure-property relationships in the direct ink writing of high-viscosity rubber nanocomposites. The goal is to optimize material composition and manufacturing process parameters to achieve high-quality 3D-printed parts with enhanced mechanical, electromechanical, and time-dependent properties. Key activities include preparing rubber compounds with various reinforced and conductive fillers, systematically varying the additive manufacturing process parameters, and experimentally characterizing the resulting microstructures and properties. This research aims to address critical knowledge gaps in understanding how material formulation and direct ink writing process variables impact the final characteristics of these versatile rubber nanocomposite parts, which have potential applications in medical devices, soft robotics, flexible electronics, and other products. No sub-awards are planned under this grant.
