Cobraiding of sensitive optical fiber sensor in 3D composite fiber network

摘要

d developments in composite structures using innovative fiber architecture has stimulated interest in novel characterization methods for 3-D braided composite materials/structures. In this paper, a compatible technique suitable for 2-D and 3-D braided structures is presented. Several samples of smart structures were designed, fabricated and tested. Results show that the developed sensing technique is sensitive and applicable to complicated composite structures. In addition, the sensors can be incorporated into the structure during the braiding process, and can be used for in-situ monitoring and feedback control of the process.
