由于先进复合材料(ACM)的出现,飞机的结构材料有了很大的变化。如果把复合材料用于飞机的主翼和机身的整体结构,则可比金属结构的重量减轻约20%,若用于舵面和机门等二级结构,则可减轻30%的重量。据美国空军下属之格拉曼公司的研究报告称,如果战斗机结构的76%使用复合材料,同金属结构相比,可以减轻35%的重量。据此,机体总重量可减轻26%,节约燃 Due to the advent of advanced composite materials (ACMs), the structural materials of aircraft have changed dramatically. If the composite is used for the overall structure of the main fuselage and fuselage of the aircraft, the weight of the composite structure can be reduced by about 20% compared with that of the metal structure. If the composite structure is used for the secondary structure such as the control surface and the door, the weight can be reduced by 30%. According to a study by Grammons, a subsidiary of the U.S. Air Force, the composite can reduce 76% of the fighter’s structure by 35% compared to metal structures. Accordingly, the total body weight can be reduced by 26%, saving fuel
