从上世纪六七十年代以来,先进复合材料在民机上的应用从无到有,从少到多,用量占比越来越大,在波音787、空客A350上的用量占比已经达到甚至超过50%。由于复合材料能带来民机结构的轻量化,并提高其可靠性、使用寿命和效能,因此可以断言,复合材料在民机上的用量占比还会进一步扩大。目前研究重点虽然复合材料在民用飞机上的应用日益广泛,但也存在一定的问题。例如,复合材料部分性能分散性大、损伤容限
Since the 1960s and 1970s, the application of advanced composite materials has grown from scratch. From less to more, the proportion of used composite materials has been increasing. The proportion of used composite materials in the Boeing 787 and Airbus A350 has reached or even exceeded Over 50%. As the composite material can bring the lightweight of civil aircraft structure and improve its reliability, service life and performance, it can be asserted that the proportion of composite materials used in civil aircraft will be further expanded. At present, the focus of research Although the application of composite materials in civil aircraft is increasingly widespread, but there are also some problems. For example, the performance of the composite part of the dispersion, damage tolerance
