| Abstract Scope |
Progress towards Additive Manufacturing (AM) of continuous-fiber reinforced SiC/SiC composites will be reviewed. The Department-of-Energy-funded project focuses on reducing the energy cost of manufacturing SiC/SiC composites utilizing AM and advanced Polymer Infiltration and Pyrolysis (PIP) for densification when compared to conventional hand-layup and Chemical Vapor Infiltration (CVI). Further energy costs will be realized when these SiC/SiC composites are implemented in the hot zone of turbine engines, allowing for higher combustion conditions and therefore more-efficient use of fuel. The AM method employed is an extrusion-deposition method (robocasting) that will allow for coextrusion of continuous fiber tows and a high-solids-loading matrix material. Aqueous carriers have been replaced with PreCeramic Polymers (PCPs) for a high-yield matrix material. |
