摘    要:以陶瓷基复合材料(CMC)为代表的纤维增韧复合材料具有耐高温、高强度、低密度等特点,在航空燃气涡轮发动机、火箭发动机等动力装置中逐步得到工程应用。CMC材料因其自身特殊的结构特点,使得其导热系数呈现出明显的各向异性,进而导致传统基于均质金属材料的热分析方法将不再适用于CMC热端部件。总结了单向纤维、2/2.5维编织纤维、3维编织纤维等典型纤维增韧CMC材料导热系数预测方法的研究进展和CMC热端部件热分析方法的研究现状。综合来看,如何在热分析中高效引入CMC材料微观尺度信息,建立起精度高且工程可应用的CMC热端部件跨尺度热分析方法是目前亟需突破的技术难题。面向未来CMC热端部件的工程应用,基于三维微观结构特征重构的热分析模型是建立CMC热端部件高精度热分析方法的关键,同时热分析还需要同制造工艺、力学行为分析等进一步紧密结合。

关 键 词:陶瓷基复合材料  热分析方法  各向异性导热系数  CMC热端部件  跨尺度热分析方法

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.
Keywords:ceramic matrix composites  thermal analysis methods  anisotropic thermal conductivity  CMC hot components  multi-scale thermal analysis methods
