Abstract

We equipped a composite wing structure fiber Bragg grating (FBG) arrays including 246 FBGs with 10 mm gauge length, eight and six long-length FBGs with 300 mm and 500 mm, respectively. The length of the wing was 6 m and it was made of carbon fiber reinforced plastics (CFRP). The sensing system based on optical frequency domain reflectometry (OFDR) was used in a series of load tests. The measured results by FBG arrays showed the overall deformation of the wing and good agreement with analysis results. Additionally, strain distributions of stress concentration zones were successfully measured by long-length FBGs.
