摘要：
An aluminum silicate nanofiber-reinforced Al2O3-SiO2 aerogel (AS/ASNFAs) has been prepared by sol-gel method.Addition of aluminum silicate nanofibers (ASNFs) improves mechanical properties of Al2O3-SiO2 aerogel (ASAs), and compressive strength of AS/ASNFAs-0.2 (0.44 MPa) is more than twice that of ASAs (0.16 MPa).Low thermal conductivity (0.026 W/(m·K)) is achieved for AS/ASNFAs-0.1.Due to the good dispersion of ASNFs in ASAs, the interaction of them not only improves mechanical properties of AS/ASNFAs but also increases thermal stability at high temperature.
