| Abstract Scope |
While ceramic matrix composites (CMCs) exhibit exceptional mechanical and thermal resilience under extreme conditions, their manufacturing process remains inefficient due to numerous time-consuming steps. Traditional methods involve prepregging fiber cloth, shaping and layering in a mold, autoclaving, and several rounds of polymer infiltration and pyrolysis (PIP). Additive manufacturing (AM) presents a promising solution by consolidating these processes into a single operation. This innovative approach involves coextruding fiber tow and preceramic matrix, facilitating in-situ fiber impregnation and streamlining production of complex-shaped CMC structures. Thus, this study focuses on optimizing the CMC manufacturing via AM and advanced PIP densification. Several traditional CMC plaques and AM CMC bars underwent various PIP methods while monitoring their mass gains and material properties. Advanced PIP combined with AM promises significant time, energy, and labor savings in CMC manufacturing, enhancing material utilization. |
