摘　　要：主要从ZrC作为基体和增强体两个方面综述了ZrC陶瓷复合材料的研究进展。重点介绍了复合材料的制备、组织和性能等研究,并就ZrC陶瓷复合材料下一步研究的重点提出了一些见解。经过分析可以看出,目前ZrC陶瓷应用中面临的主要问题是韧性低、难以烧结致密。在今后ZrC陶瓷的研究过程中,如能克服和改善其缺点,注重开发ZrC陶瓷材料潜在的性能优势,则必将使ZrC陶瓷在航空、航天等的发展中做出重要贡献。ZrC ceramic composites are reviewed from two aspects -- ZrC as matrix materials and rein{orcement materials. Research on the fabrication, microstructure and properties of the composites are detailedly introduced, and the main research direction of ZrC ceramic composites is also proposed. It can be concluded that the main problems in the application of Zff2 ceramic are low fracture toughness and poor sintering densification. In future studies on ZrC ce- ramics, if the drawbacks are overcome and improved, and the development of potential performance advantages for ZrC ceramic materials is given considerable attention, ZrC ceramic will make an important contribution to the develop- ment of aviation and aerospace field.
