文摘 作为一种先进的高温结构及功能材料,高效传热和高温耐热相结合对纤维增强碳化硅陶瓷基复合材料(silicon carbide matrix composites, SiC CMC)在热管理领域(thermal management,TM)中的应用至关重要。常见的纤维增强碳化硅陶瓷基复合材料,如碳纤维增强碳化硅陶瓷基复合材料(Cf/SiC或Cf/C-SiC)、碳化硅纤维增强碳化硅陶瓷基复合材料(SiC_f/SiC)等,增强纤维的石墨化程度较低,难以形成有效的热输运网络。本文综述了纤维增强碳化硅陶瓷基复合材料制备及高导热性能等方面的最新研究进展。可通过引入高导热相、优化界面结构、粗粒化碳化硅晶体、设计预制体结构等方式提高纤维增强碳化硅陶瓷基复合材料的热输运能力。此外,展望了纤维增强碳化硅陶瓷基复合材料发展趋势,即综合考虑影响高导热碳化硅陶瓷基复合材料性能要素,灵活运用复合材料结构与性能的构效关系,以期制备尺寸稳定、性能优异的纤维增强碳化硅陶瓷基复合材料。
其他语种文摘 As one kind of advanced high temperature structural and functional materials, it is necessary for fiber reinforced silicon carbide matrix composites (SiC CMCs) in the field of thermal management (TM) to combine the efficient heat transfer and high temperature heat resistance. Common fibers reinforced SiC CMCs, such as carbon fibers reinforced SiC CMCs (Cf/SiC or Cf/C-SiC),silicon carbide based fiber reinforced SiC CMCs (SiC_f/SiC),etc.,have a low degree of graphitization of the reinforcing fiber and are difficult to form an effective heat transport network. The latest research progress on the preparation and properties of fiber reinforced SiC CMCs with highly thermal conductivity was reviewed in this paper. The heat transport ability of fiber reinforced SiC CMCs can be improved by introducing highly thermal conductive phase,optimizing interfacial structure,making silicon carbide crystal coarse-grained, and designing preform structure. Moreover, the development of the fiber reinforced SiC CMCs with highly thermal conductivities was prospected, that is, comprehensively considering the factors that affect the performance of SiC CMCs,flexibly using the structure-activity relationship between the microstructure and properties of the composites,in order to prepare fiber reinforced SiC CMCs with stable size, excellent properties.
