Abstract

The use of intensity-based optical fiber systems and fiber Bragg grating sensor for damage detection in composite structures was investigated. These optical fiber systems were found to be capable of detecting impact damage, transverse cracking and delamination and also have the ability to monitor strain in structures. It was found that it is important that optical fibers should be embedded parallel to adjacent plies to prevent physical discontinuity within the composite lay-up. The results show that the coating material and thickness play a significant role in the overall influence on the material properties.
