Development of multi-functional coaxial fiber sensor for simultaneous strain and temperature monitoring for composite manufacturing process

초록

Coaxial structured fibers have gained significant attention in sensor applications due to their design flexibility and ability to enable multi-functionality. However, when utilized for strain monitoring in composite manufacturing processes, the sensor's complex and thicker structure can lead to stress concentration and signal interference. To address this issue, we propose a multifunctional coaxial fiber sensor capable of simultaneous temperature and strain measurement during composite manufacturing process. To achieve multi-functional sensing, we employ a multi-shell structure consisting of a multi-conductive layer and PEDOT:PSS layer, applied to a creep-enhanced ultra-high molecular weight polyethylene core fiber using a simple dip-coating method. © 2025 ICCM24.All rights reserved.
