Abstract

The invention relates to a fiber grating intelligent plate made of fiber reinforced polymer in a pulling extrusion and continuous forming mode and a manufacturing method thereof. The intelligent plate has civil engineering structural stress and self-monitoring double functions. The intelligent plate comprises a plate body composed of fiber grey yarns and matrix resin, wherein the plate body is filled with sensor fibers containing fiber grating sensors and transmission fibers in the fiber direction, the number of the sensor fibers is m, m is an integer larger than or equal to one, each sensor fiber is provided with n fiber grating sensors, and n is an integer larger than or equal to one. The intelligent plate is manufactured in a pulling extrusion and continuous forming process, the fiber volume content of the intelligent plate is no less than 60%, and the intelligent plate facilitates accurate control of tension control stress of fiber plates, compensation of lost prestress and real-time monitoring of reinforced structures when the fiber plates, especially prestress fiber plates are used for reinforcing and repairing concrete structures and steel structures.
