摘要:

为研究经编光纤传感织物在纵向拉伸状态下织物结构变化对光纤弯曲损耗的影响,编织了一种以经平绒织物为地组织、聚合物光纤为衬纬纱的经编光纤传感织物。将光纤以半径为10 mm 的半圆反向相接的形式织入地组织中间位置,形成传感单元。同时,测量了传感织物在拉伸条件下的线圈高度、线圈宽度和织物厚度;并测试了在织物拉伸回复状态下光纤信号的传输性能。结果表明:光纤可通过衬纬的形式与经编织物相结合;在拉伸过程中织物纱段发生转移,织物厚度随拉伸距离的增加而减小;纱线对光纤的挤压作用使光纤产生微弯损耗,且在拉伸过程中微弯和宏弯损耗相互复合。

Abstract:

In order to study the influence of the fabric structure change of the warp-knitted optical fiber sensing fabric on the bending loss of the optical fiber inlaid during longitudinal stretching, a warp-knitted fiber sensing fabric with a locknit construction as the ground structure and an polymer optical fiber as the inlay yarn was knitted. A section of polymer optical fiber was inlaid into the ground structure in a form of two reverse connected semicircles with a radius of 10 mm, forming a sensing unit. Stitch height, stitch width and fabric thickness under tensile loading were measured, and the signal transmission property of the optical fiber was tested. Experiment results show that the optical fiber can be combined with warpknitted fabric in the form of weft insertion. During stretching process, yarn sections of the ground structure are transferred and fabric thickness decreases with the increase of the stretching distance. The pressing effect of the knitting yarns on the optical fiber causes the micro-bending loss of the optical fibers,
and the microbending and macrobending losses are compounded during stretching process.
