摘　　要：氧化铝陶瓷连续纤维具有耐高温、高强度、高模量、热导率低、绝缘性好、耐化学腐蚀能力强等特点,在航空航天、先进制造等领域具有重要的应用。本文对氧化铝基陶瓷连续纤维的制备、性能及应用进行了全面的综述,并对氧化铝基陶瓷连续纤维未来的发展方向进行了总结和展望,期望为未来氧化铝基陶瓷连续纤维的研制与应用提供参考。Alumina ceramic continuous fiber is one of the most important materials because of its high strength and modulus,high temperature resistance,chemical inertness in both oxidizing and reducing atmospheres even at high temperature,resistance to attack from non-oxide materials,good electrical insulation and low thermal conductivity.The high strength and high-temperature resistance have allowed the development of metal and ceramic matrix composites with high tensile strength or high-temperature load-bearing capability.Thus,alumina ceramic continuous fiber is of great importance in aerospace,advanced manufacturing,and other fields.The Al_(2)O_(3) content in alumina ceramic fiber is usually more than 70 wt%,and generally contains a small amount of other oxides,such as SiO_(2),B_(2)O_(3),Fe_(2)O_(3),ZrO_(2),and etc.Amorphous SiO_(2),transition phase alumina,a-Al_(2)O_(3) and mullite are the common phases in alumina ceramic fibers,resulting in various phase compositions and microstructures.Chemical composition and the microstructure have great effects on the fibers’mechanical performance and temperature resistance.Depending on the chemical composition and the microstructure,the alumina ceramic fibers show the tensile strength from 1.5 GPa to 3.1 GPa,and a long-term using temperature varied from 1000 to 1300℃.The careful selection is necessary according to the unique circumstances and conditions involved in the use and processing of the alumina fibers.Furthermore,the preparation of alumina ceramic fibers with controlled composition and microstructure is critical.Main methods for manufacturing alumina ceramic fibers can be classified as slurry process,melt-spinning process,prepolymerization process and sol-gel spinning process.The melt spinning method was limited in the length of the fibers,thus,it was not suitable for the preparation of the alumina continuous fibers.While it is difficult to prepare alumina fibers with high strength from the slurry method.Excellent alumina continuous fibers can be obtained through the p
