Intelligent carbon board prepared from fiber reinforced plastics and preparation method of intelligent carbon board

Abstract

The invention discloses an intelligent carbon board prepared from fiber reinforced plastics and a preparation method of the intelligent carbon board. The intelligent carbon board comprises a fiber grating sensor, a coating part and an anchoring assembly, wherein the coating part is arranged on the outer side of the fiber grating sensor, the anchoring assembly is arranged on the outer side of the coating part, the coating part is made of fiber reinforced plastics, and the fiber grating sensor is connected with a fiber grating demodulator through a test jumper wire. According to the intelligent carbon board and the preparation method, the fiber grating sensor and the coating part are organically combined, so that a complex procedure for externally attaching sensors is reduced, the mounting error of the sensors is eliminated, the survival rate of the sensors is guaranteed, and engineering monitoring requirements are met. The intelligent carbon board can be widely applied to safe state monitoring of structural engineering of buildings and bridges.

Description

technical field [0001] The invention belongs to the technical field of building and bridge structural engineering safety monitoring, and in particular relates to a fiber-reinforced plastic intelligent carbon plate and a preparation method thereof. Background technique [0002] Prestressed carbon fiber plate, as a reinforcement structure to improve the strength and self-stabilization ability of the building and bridge structural system, has the advantages of convenient construction and simple operation, and has been widely used in bridges and construction projects, such as Henan Lianhuo Expressway In the reinforcement project, prestressed carbon fiber panels were used to reinforce concrete T beams and hollow slab beams to improve the bearing capacity of the beam structure of Henan Lianhuo Expressway. However, the steel plate reinforcement commonly used in engineering still has the disadvantages of heavy weight, difficulty in transportation and installation, difficulty in cutt...

Problems solved by technology

However, the test method still has the following limitations: ①The bare grating or optical fiber surface-attached sensor layout process has the fatal defect that the sensor and transmission line are easily damaged, and it is difficult to adapt to the extensive construction requirements; ②The adhesive used for the sensor paste layout , there is no basic guarantee for its durability, and it is impossible to ensure the long-term stable monitoring of the stress state of the carbon plate;
