中文摘要英文摘要

连续纤维增强陶瓷基复合材料具有高强韧、耐氧化的特性,现己成为航空航天领域重要的高温结构候选材料.反应熔渗法可实现陶瓷基复合材料的大规模、短周期和低成本制备,是目前最具有商业化前景的技术之一.然而,传统反应熔渗法制得陶瓷基复合材料存在着基体碳残留、纤维刻蚀等问题,导致材料力学与氧化-烧蚀性能不佳.为突破传统碳基体陶瓷化程度低的局限性,相关研究人员采用碳基体孔结构构筑方法,通过多孔碳基体取代传统熔渗预制体中致密碳基体,以促进碳基体的陶瓷化转变及反应熔体的消耗,进而实现陶瓷基复合材料的性能优化.本综述介绍了采用多孔碳陶瓷化策略制备SiC陶瓷、SiC/SiC复合材料、C/SiC复合材料及超高温陶瓷基复合材料的相关研究进展,并且通过与传统反应熔渗法对比,验证了多孔碳陶瓷化策略的优势,同时总结了相关多孔碳基体制备方法的发展演变过程,最后针对先进陶瓷基复合材料的基础理论与工艺技术需求,对多孔碳陶瓷化改进反应熔渗法的未来发展方向进行了展望.

Owing to the high strength/toughness and excellent anti-oxidation ability,continuous fiber reinforced ceramic matrix composites have become the preferred candidates for high temperature structural materials in aerospace field.Reactive melt infiltration can achieve the large-scale,short-cycle and low-cost production of ceramic matrix composites,which has been widely considered to be one of the most promising technologies from a commercial perspective.However,the mechanical and anti-oxidation/ablation properties of obtained composites prepared by conventional reactive melt infiltration are not satisfactory due to the existence of residual carbon and corroded fibers.In order to address the problems,relevant researchers constructed porous carbon matrix to replace conventional densified structure to promote its ceramic transformation and the consumption of reactive melt,thus achieving the improved performance of ceramic matrix composites.This paper reviewed the research progress about the preparation of SiC ceramics,SiC/SiC composites,C/SiC composites,and ultra-high temperature ceramic matrix composites by porous carbon ceramization strategy.Besides,the superiority of the method was verified compared to conventional reactive melt infiltration.The development of preparation methods for porous carbon matrix was also summarized.Finally,in term of the requirements of basic theory and technology for advanced ceramic matrix composites,the prospect for the future development of improved reactive melt infiltration to prepared ceramic matrix composites was discussed.
