复合材料以其比强度高、比刚度大、抗疲劳性能好及材料性能可设计等一系列优点,在航空、航天、汽车等工程领域得到了日益广泛的应用,尤其是在军用、民用飞机上已开始越来越多地使用先进复合材料结构,波音787客机上的用量已高达50%。然而,层合板复合材料在服役过程中不可避免地要承受各种冲击,极易造成复合材料结构的内部损伤并导致其力学性能退化,承载能力降低。因此对航空复合材料结构进行冲击监测,确保结构的稳定性和
Composite materials with its high strength, stiffness, fatigue resistance and material properties can be designed and a series of advantages in the field of aviation, aerospace, automotive engineering has been more widely used, especially in military, civilian aircraft Increasingly, advanced composite structures have begun to be used, with up to 50% usage on the Boeing 787 passenger aircraft. However, the laminated composite inevitably suffered various impacts during service, which could easily lead to the internal damage of the composite structure and lead to the degradation of its mechanical properties and reduce the carrying capacity. Therefore, the impact of aviation composite structures to monitor the structure to ensure structural stability and
