Abstract

In order to solve the problem of fragility of optical fibers, the extraction mode and extraction protection of the lead-out section of the optical fiber embedded in carbon fiber composite material was studied. The fsFBG sensor was embedded into the carbon fiber composite laminate by prepreg laminates manual laying, and the carbon fiber composite material was formed using a vacuum bag-assisted molding method in a heated curing oven. During the test, the fsFBG sensor was laid axially at different angles to the carbon fiber filaments in the unidirectional prepreg laminates, and embedded between the layers of carbon fiber composite, and the cross-section of the molded material was observed through the microscope, and it was found that when the sensor axially was parallel to the carbon fiber filaments, the resin-rich area around the fiber was the smallest. The research conclusions can provide a certain technical reference for the implementation of optical fiber detection of composite material.
