Combination of high-strength FBG and carbon fiber are proposed aiming at the poor performance of fiber Bragg grating (FBG) in engineering applications. The structure of the sample is introduced and the strain transmission process of sample is analyzed. Experiments were conducted to verify the strain sensing characteristic and fatigue property. Experimental results show that the composited samples can achieve high strain transmission efficiency and obtain good strain sensing characteristics. During the fatigue experiment, the samples work properly and the amplitude of wavelength change was stable. The strain sensing characteristics of samples remain essentially unchanged after the fatigue experiment, and the strain sensitivity coefficient is 1.12 and 1.17pm/με, respectively. The linearity is higher than 0.999, and the repeatability are 0.623% and 0.397%, respectively.
