复合材料能提供比金属材料更好的结构性能,但飞机的选材需要十分慎重,飞机设计师在采用先进的复合材料制造零部件时,往往忽略了制造成本,特别是与新材料使用有关的维修性能、维修技术和维修成本,而且从维修程序和成本角度看,飞机材料的选用还有很大的改进空间 Composites offer better structural performance than metallic materials, but the selection of aircraft is a matter of prudence. Aircraft designers often neglect manufacturing costs when manufacturing components from advanced composite materials, especially those related to the use of new materials Performance, maintenance technology and maintenance costs, but also from the maintenance procedures and cost perspective, the selection of aircraft materials, there is still much room for improvement
