| Abstract Scope |
Recent advances in additive manufacturing, combined with traditional infiltration processes, have enabled the fabrication of ceramic components with complex shapes, which until recently had not been possible with conventional manufacturing processes. In this presentation, we report results from the characterization and evaluation of silicon carbide composites fabricated by additive manufacturing using binder jet 3D printing followed by phenolic polymer impregnation and pyrolysis (PIP) and reactive silicon melt infiltration (RMI). The ability of increasing the SiC content is demonstrated, and the role of microstructure on thermal, mechanical, and physical properties including thermal conductivity, specific heat, thermal expansion coefficient, and flexural strength is discussed. While these materials have the potential for utilization in a wide range of technologies and applications, the case of heat exchangers for high-temperature applications has been considered and relevant properties have been determined accordingly. |
