摘　　要：Al_(2)O_(3)-SiO_(2)气凝胶(ASA)因具有孔隙率高、密度低、比表面积高等特性,耐高温和隔热性能较为突出,在航空航天隔热领域具有广阔的发展前景。然而,ASA的力学性能相对较差和高温下对红外辐射吸收和散热能力较弱等问题,限制了其在高温隔热领域的应用;元素掺杂和纤维增强是目前改进ASA隔热性能和力学性能的常用方法。本文从ASA的制备技术、ASA性能的影响因素、元素或物质掺杂ASA的研究及纤维增强ASA复合材料四个方面进行了综述,并对ASA未来发展方向做出了展望。The Al_(2)O_(3)-SiO_(2)aerogel(ASA),due to its high porosity,low density and high specific surface area,exhibits outstanding high-temperature resistance and thermal insulation properties,holding broad development prospects in the field of aerospace thermal insulation.However,the relatively poor mechanical properties of ASA,weak infrared radiation absorption and heat dissipation capabilities at high temperatures limit its application in the field of high-temperature insulation.Element doping and fiber reinforcement are commonly used to improve the thermal insulation and mechanical properties of ASA.This paper provides an overview of ASA preparation techniques,factors affecting ASA properties,research on element or substance doped ASA,and fiber-reinforced ASA composites,while also offering insights into the future development directions of ASA.
