Preparation and performance characterization of intelligent woven composites embedded with distributed fiber optic sensors
Source abstract
Abstract
Advanced composite materials play a critical role in enhancing the lightweight performance of high-end equipment structures. However, during service, composite structures may experience various forms of damage, posing threats to structural safety. Aiming to meet future demands for integrated structural health monitoring and load-bearing capabilities in composite structures, this study investigates intelligent woven composite structures embedded with distributed fiber optic sensors . A high-efficiency, low-damage preparation method for hybrid preforms combining optical fibers and quartz fibers was developed, based on the weavability study of optical fibers. A mold with fiber optic sensor outlet protection was designed, and intelligent composite specimens with embedded distributed fiber optic sensors were fabricated using the resin transfer molding process. The effects of embedded optical fiber on the tensile and interlaminar shear properties of the composites were evaluated, and three-point bending test was conducted on the specimen to validate its load-bearing performance and strain self-sensing capabilities. This work can provide technical support for the development of intelligent composite structures that integrate health monitoring and load-bearing functionalities.
