Summary
A new process of ceramic matrix composite production, named Nano-powder Infiltration and Transient Eutectoid (NITE) process, has been developed and unidirectional SiC/SiC composites were prepared, and the effects of densification conditions on the microstructural evolution and mechanical properties were investigated. Carbon coated fibers were used as reinforcement and SiC nano-powders were used for matrix formation with certain amount of sintering aids. Density of the composites was improved with the increment of either temperature or pressure. Simultaneously, the interaction between fibers and matrix became strong. Highest tensile strength was obtained at 1780C under 20MPa in this work. Many potential advantages of the NITE process were demonstrated; promising mechanical properties, moderate to high thermal conductivity, extremely low gas permeability and low production cost.
