| Abstract Scope |
Continuous fiber ceramic matrix composites (CMCs), particularly SiC/SiC systems, are promising candidates for high-temperature structural applications due to their exceptional thermal stability, corrosion resistance, and damage tolerance. However, achieving consistent microstructures and reliable mechanical performance through scalable manufacturing routes remains challenging. This work investigates the fabrication of SiC ceramic composite tubes using filament winding, vacuum infusion, and pyrolysis, focusing on how processing routes influence porosity, fiber alignment, and fracture behavior. Tubes were produced with both helical (±45°) and hoop winding patterns, using wet and dry winding approaches, followed by infusion with phenolic or PVA resin systems. Selected specimens were further densified with SiC chemical vapor infiltration (CVI). Microstructural evolution was tracked through successive processing stages using techniques such as X-ray computed tomography (CT), scanning electron microscopy (SEM), and optical microscopy. The findings provide insights into optimizing the performance and scalability of CMCs for demanding high-temperature applications. |
