摘　　要：连续氧化铝纤维是新一代耐高温热端构件主力原材料,具备熔点高、热导率低、绝缘性好、抗化学侵蚀能力强及高比强等特性。该材料用于制备耐高温高强、防隔热陶瓷基复合材料,广泛应用于航空、航天、船舶、热电、石油化工、半导体、汽车以及高温炉膛等高端领域。国外氧化铝纤维及其复合材料已形成产品化并实现了构件应用,国内在该领域起步较晚,近10年左右时间实现了从基础研究到应用研究的跨越式发展。本文归纳介绍了国内外氧化铝纤维及其复合材料的发展历程、制备工艺、研究现状及产业布局情况,并提出了当下存在的问题以及后续发展重点。continuous alumina fiber is the main raw material of a new generation of hightemperature resistant hot-end components due to its high melting point,low thermal conductivity,good insulation,strong resistance to chemical erosion and high specific strength.This material is used to prepare high-temperature-resistant,high-strength,anti-heat-insulating ceramic matrix composite materials,which are widely used in high-end fields such as aviation,aerospace,shipbuilding,thermoelectricity,petrochemicals,semiconductors,automobiles,and high-temperature furnaces.Alumina fiber and its composite materials abroad have been commercialized and implemented in component applications.Significant strides has been made domestically in this field over the past decade by transitioning from basic research to applied research.This paper summarizes the research progress on preparation,industrial layout of alumina fiber and its composites.Finally,the key problems and future development emphases of the alumina fiber and its composites are proposed.
