复合材料是由两种或两种以上材料独立物理相,通过复合工艺组合构成的新型材料。其中,连续相为基体,分散相为增强体,两相彼此之间没有明显的界面。它既保留原组分材料的主要特点,又通过复合效应获得原组分材料所不具备的性能。通过材料设计可以使各组分材料的性能互相补充、彼此联系,从而获得优越性能。先进复合材料已经大量应用于民用飞机结构中,空客A380飞机复合材料用量占飞机结构重量的24%(不含GLARE层板),波音B787飞机复合材料用量占飞
Composites are new types of materials composed of two or more materials that are physically independent and are made from a combination of composite processes. Among them, the continuous phase is the matrix, the dispersed phase is the reinforcement, there is no obvious interface between the two phases. It not only retains the main features of the original component materials, but also through the composite effect of the original component materials do not have the performance. Through the material design, the performance of each component material can be complemented with each other to obtain superior performance. Advanced composite materials have been widely used in civil aircraft structures. Airbus A380 composites accounted for 24% of the aircraft’s structural weight (excluding GLARE laminates), and the amount of composite material used for the Boeing B787 aircraft accounted for
