The Fiber Bragg Grating(FBG) sensors in the center of die are pultruded with fiber strands in the production of Fiber Reinforced Polymer(FRP) bars,and the smart Fiber Bragg Grating-Fiber Reinforced Polymer(FBG-FRP) anchor tendons are produced.

• 在纤维增强塑料筋制作过程中,将光纤光栅传感器埋入其内部,可得到光纤光栅纤维增强塑料筋锚杆,它兼具受力与传感的特性,集结构和功能于一体。
