Abstract

The application provides a coupling fiber grating wide-range intelligent carbon fiber rib which is provided with at least one spiral groove. The spiral grooves are internally provided with optical fiber lines and optical fiber protective layers which are used for covering the optical fiber lines. Multiple strain gratings and temperature gratings are carved on the optical fiber lines. The application also provides a manufacturing method of the coupling fiber grating wide-range intelligent carbon fiber rib. The problem of limitation of measuring range of stress and strain monitoring of existing optical fiber gratings in the use process of the carbon fiber rib can be solved by the coupling fiber grating wide-range intelligent carbon fiber rib and the manufacturing method thereof.

Description

technical field [0001] The application belongs to the technical field of monitoring, and in particular relates to a large-scale intelligent carbon fiber bar coupled with a fiber grating and a manufacturing method thereof. Background technique [0002] Various structures such as building structures, bridge structures, underground structures, marine structures, etc. are coupled by various effects of the environment and loads during their service period, inevitably causing damage and accumulation, and they need to be repaired when necessary and reinforcement. Prestressed carbon fiber reinforcement is widely used in the maintenance and reinforcement of various structures and components because of its advantages of high strength, light weight, good durability, and easy construction. It is of great significance to monitor the stress and deformation state during the reinforcement process. . Fiber Bragg grating technology perceives small changes in external physical quantities suc...
