- Abstract
- Fiber-optic sensors (FOS) based on fiber Bragg gratings (FBG), methods of their integration into polymer composite materials (PCM) and control of their characteristics are considered. The directions of FOS development for quality control of elements and assemblies of articles of aircraft products made of PCM are identified. The maximum permissible impacts on optical fiber and sensors based on it have been determined. The trend in the manufacture of multi-sensor FOS designs based on monolithic fiber with FBGs written in the core or miniature designs for the simultaneous operation of two to four or more independent sensors on one fiber without increasing the transverse dimensions of the fiber sensor is analyzed. The possibility of using an extended integral fiber as a distributed multi-sensor sensitive element built into the structure of an aircraft wing or into the body of a space craft is revealed. The possibility of creating fiber-optic acoustic emission sensors (FOS AE) for monitoring the strength and durability of CM structures with embedded optical fibers has been revealed and experimentally confirmed.
