摘要

先进复合材料在提高高端装备结构轻量化性能方面发挥着至关重要的作用。然而，在使用过程中，复合结构可能会出现各种形式的损伤，对结构安全构成威胁。为了满足未来复合材料结构综合健康监测和承载能力的需求，本研究对嵌入分布式光纤传感器的智能编织复合材料结构进行了研究。在研究光纤可织性的基础上，提出了一种高效、低损伤的光纤与石英纤维复合预制品制备方法。设计了具有光纤传感器出口保护的模具，采用树脂传递成型工艺制作了嵌入式分布式光纤传感器的智能复合试件。研究了光纤埋入对复合材料拉伸和层间剪切性能的影响，并对试件进行三点弯曲试验，验证了其承载性能和应变自感知能力。该工作可为发展集健康监测和承重功能于一体的智能复合结构提供技术支持。

Preparation and performance characterization of intelligent woven composites embedded with distributed fiber optic sensors

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.

期刊介绍： Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
