Progress on Anti-Powder-Peeling Performance of Silica Aerogels and Their Composites for Aircraft
As the most mature high-temperature resistant and high-efficiency thermal insulation material in aerogel,silica aerogel is widely used in aerospace,national defense and military industries,but due to its intrinsic characteristics of brittleness and flexibility,resulting in completely losing function derived from the phenomena of powder-peeling and residue-peeling even direct crushing under the impact and vibration loading conditions,further degrading the thermally in-sulating performance of silica aerogels and obviously limiting its practical application.Therefore,how to promote the anti-powder-peeling performance of silica aerogels has currently become a hot topic.The latest research progress at home and abroad to improve the flexibility of silica aerogels is introduced,and the main feasible strategies to improve the anti-powder-peeling performance of silica aerogels in recent years are systematically expounded,in order to solve the practical problems of the material for a long time,such as powder-peeling and residue-peeling of silica aerogels.Ultimately the re-view prospects the development trends of silica aerogels in further enhancing anti-powder-peeling performance domain.
