4, high-performance thermal wave-transparent materials
High-performance thermal wave-transparent materials for aircraft radome (window), the early main quartz ceramics, alumina ceramics, microcrystalline glass, etc., and later developed a higher reliability of quartz fiber-reinforced silicon oxide composite materials. As the speed of the aircraft is getting higher and higher, the flight time is getting longer and longer, the demand for high temperature and long time wave-transparent materials is getting more and more urgent, nitride fiber reinforced ceramic composites have become the hot spot of high temperature wave-transparent materials.
5、High temperature and high efficiency heat insulation materials
The flight speed of hypersonic vehicle is increasing, the flight time is longer, the demand for high temperature and high efficiency heat insulation materials is more urgent. Existing mature thermal insulation materials, such as ceramic tiles, thermal insulation felt, oxide nano-insulation materials, the use of temperature can not meet the future requirements of the aircraft. Carbon and carbide porous heat insulation materials in an inert environment with excellent thermal stability and heat insulation performance, has become the focus of domestic and foreign research on ultra-high-temperature heat insulation materials.
6、Resin-based structural composites
Resin-based structural composites have high specific strength and specific modulus, which can realize the structural lightweighting of carrier rockets, satellites, missiles, etc., and their dosage is also one of the indexes to measure the structural advancement of spacecraft. After years of development, the matrix has been formed for the epoxy resin, bimatrix resin and polyimide resin on behalf of the structure of the composite material series. With the development of high-performance carbon fibers and new resins in recent years, the load-bearing, processability and stability of resin-based structural composites have been gradually improved. Figure 11 shows the NANOALLOY® nanoscale blending technology developed by Toray, Japan, to develop a new high-strength and high-modulus resin matrix, which significantly improves the performance of composite materials.
