Abstract: Ceramic Matrix Composite (CMC), one of the fiber reinforced composites, has been increasingly applied in power devices such as aero gas turbine engines and rocket engines because of its excellent heat-resistance and mechanical performance. The thermal properties of the CMC exhibit obvious anisotropy due to the internal structural and the difference between matrix and fibers. Therefore, the traditional thermal analysis method based on homogeneous metal materials for hot components is no longer suitable for CMC hot components. This paper summarizes the CMC thermal conductivity prediction methods for different internal structures, including the Unidirectional Fiber Reinforced Composites (UFRC), the 2D/2.5D Weave Composites (TDWC) and the 3D Braided Composites (TDBC). Currently, a multi-scale thermal analysis method of CMC hot components with high accuracy which is applicable in engineering is a technical problem to be solved. For future engineering applications of CMC hot components, a thermal analysis model based on the reconstruction of three-dimensional microstructure characteristics is the key to establishing a high-precision thermal analysis method for CMC hot components. Meanwhile, thermal analysis needs to be further closely integrated with manufacturing processes and mechanical behavior analysis.
