Problems solved by technology

[0006] When there is no special template for hot pressing, the commonly used FRP prepreg is opaque, and the sensor after hot pressing cannot accurately locate the FBG grid area in the cured fiber-reinforced composite material, which affects the accurate positioning of the monitoring point during subsequent use; In addition, high-volume high-quality FBG packaging cannot be performed without a dedicated hot-pressing mold

Abstract

The invention discloses an FRP-FBG (Fiber Reinforce Plastic-Fiber Bragg Grating) packaging device and a positioning method. The packaging device has the beneficial effects that the residual stress ofoptical fibers can be reduced through tensioning mechanisms and the tensioned optical fibers can also keep straight and are not easy to be bent, twisted or deformed during processing to ensure that amanufactured sensor is high in quality and efficiency. The positioning method has the beneficial effects that in the sensor, a gate region is wrapped and by adopting the positioning method, the gate region is easily guaranteed to be at the center position during the processing and the position of the gate region can be re-marked on the sensor to provide convenience for later installation and use.The device disclosed by the invention is used for the field of sensor packaging.

Description

technical field [0001] The invention relates to the field of sensor packaging, in particular to an FRP-FBG packaging device and a positioning method. Background technique [0002] FBG: Fiber Bragg Grating sensor, Fiber Bragg Grating. [0003] FRP: Fiber reinforced composite material, Fiber Reinforced Plastics. [0004] FBG is a kind of fiber optic sensor. The principle of the sensor is to obtain sensor information through the modulation of the fiber Bragg wavelength by the external physical quantity. It is a wavelength modulation fiber grating sensor. Fiber Bragg grating sensors can realize direct measurement of physical quantities such as temperature and strain, and can be attached to the surface of the structure or embedded in the structure in advance to perform health detection, impact detection, shape control and vibration damping detection on the structure at the same time, as well as analyze the structure. defective condition. In recent years, fiber grating sensors ...
