Abstract Scope |
Creating more robust additive manufacturing routes for Air Force applications requires a detailed physics-based understanding of the process. The effects of printing parameters, environment and interplay between constituents during an extrusion-based process that creates complex shaped parts are crucial to the performance that can be achieved via additive manufacturing. Mapping both dynamics and morphology in real time is essential to understand the limitations of the process and to eliminate key bottlenecks. We use X-ray Photon Correlation Spectroscopy to capture fast processes and the shear induced morphological evolution of polymer and fillers during Direct Write and Fused Filament Fabrication of polymer matrix composites. The findings of these experiments may lead to the redesign of nozzle geometries and surfaces to obtain improved road to road bonding. |
