SiC/SiC复合材料因其高温稳定性而有望用作高温结构件材料。东芝开发了两种用于燃气轮机热部件应用的 SiC/SiC 复合材料，采用 RS 和 PIP 工艺生产。这两种工艺都具有近净制造复杂形状的能力。在这项工作中，采用压汞法评估了两种SiC/SiC复合材料的微观结构。讨论了其微观结构特征对其弯曲强度、导热性和抗氧化性等性能的影响。
SiC/SiC composites are expected to be used as materials for high temperature structural parts because of their high temperature stability. Toshiba has developed two kinds of SiC/SiC composites for gas turbine hot parts applications, which produced by RS and PIP processes. The both processes have the capabilities of making complex shapes in near net. In this work, the microstructure of two kinds of SiC/SiC composites was evaluated using mercury intrusion method. The influence of their microstructural feature on some properties, such as bending strength, thermal conductivity and oxidation resistance, were discussed.
