一种新型液芯光纤及其性能研究

摘要

目前绝大部分复合材料仿生自修复方法中, 使用的承载修复剂的修复媒介只能实现自修复而无法感知损伤.针对这一问题, 设计出一种新型液芯光纤, 并对该种液芯光纤的传输损耗进行了理论分析和实验验证, 测定了液芯光纤的衰减系数, 同时对液芯光纤的承载性能进行了研究, 为该新型液芯光纤作为传感元件在复合材料智能结构中的应用提供实验依据.%Aiming at the problem that most of the bionic self-healing composite method used in the repair of bearing repair agent medium can only achieve self-healing and imperceptibility injury problems, this paper designed a new type of liquid core optical fiber, and the transmission loss of this kind of liquid core optical fiber has been studied theoretically and experimentally.The determination of the liquid core optical fiber attenuation coefficient, as well as the bearing capacity of liquid core optical fiber were studied.The study can serve as experimental basis for this type of new liquid core optical fiber as the sensing element in the application of intelligent composite material structure.
