| Abstract: | In order to achieve continuous monitoring the health state of three-dimensional braided composite materials,the fiber Bragg grating(FBG) sensor has been embedded in composite material specimens based on braiding process.The paper analyzes relations between internal strain of the composite material and FBG signal under tension load.The results show that there is a good linear relationship between FBG strain sensor signal and specimen strain.The surface braiding angle of three-dimensional braided composite ha... |
| Keywords: | 3D braided composite braided method fiber Bragg grating sensor tensile strain |
