具有健康监测功能的智能复合材料结构在航空航天、舰船武器等军事领域和机械结构、土木工程等民用领域得到了初步应用。其中光纤传感系统由于具有柔软、电绝缘、耐腐蚀、和复合材料具有良好的耦合性等许多独特的优点,常用于智能材料结构的应力、变形等物理量的检测中,成为构成智能复合材料结构中自诊断系统的首选功能元件。在光纤智能结构中,由于光纤传感器的埋入,导致了材料几何上的不连续,从而不可避免地会对埋入光纤附近 The intelligent composite structure with health monitoring has been initially applied in civil fields such as aerospace, naval weapons and other military fields as well as mechanical structures and civil engineering. The optical fiber sensing system has many unique advantages such as softness, electrical insulation, corrosion resistance, good coupling with composite materials and the like, and is often used in the detection of physical quantities such as stress and deformation of a smart material structure to become an intelligent composite material structure The first choice of self-diagnostic system components. In the optical fiber smart structure, due to the embedding of the optical fiber sensor, the geometric discontinuity of the material is inevitably brought about in the vicinity of the embedded optical fiber
