摘　　要：纤维复合材料(FRP)具有轻质、高强、耐腐蚀、抗疲劳及良好的自传感特性等优点。将FRP与光纤光栅传感技术相结合,即在FRP材料加工过程中埋入光纤光栅传感元件(OFBG)可制成新型自监测复合材料(OFBG-FRP)。OFBG-FRP兼有FRP优良的物理力学性能及光纤光栅的智能传感特性。本文主要介绍FRP及OFBG-FRP的传感特性及其在土木工程健康监测中的应用等方面的研究进展。Fiber reinforced polymer （FRP） strength , excellent corrosive resistance and fatigue not only presents many advantages such as light weight, high resistance, but also exhibits good self-sensing properties. In addition, a new kind of sensing material, OFBG-FRP, can be made by combining FRP and sensing technique of optic fiber grating. OFBG-FRP has both the excellent mechanical properties of FRP and intelligent sensing properties of optic fiber grating. This paper mainly introduces the sensing properties of FRP and OFBG-FRP. The correlative research progress of their application in the health monitoring is also presented.
