FIBER-REINFORCED COMPOSITE MATERIAL STRUCTURE AND METHOD FOR MANUFACTURING FIBER-REINFORCED COMPOSITE MATERIAL STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a fiber-reinforced composite material structure capable of controlling and suppressing the flexure of reinforced fibers, and evaluating distortion with high density and high accuracy even when an optical fiber sensor is internally embedded in a state that reinforced fibers are oriented in a plurality of directions and a method for manufacturing the fiber-reinforced composite material structure.SOLUTION: An optical fiber sensor structure (2) in which a taper resin layer (5) is formed in the periphery of an optical fiber (3) is formed is embedded between the layers of prepreg (between the layers of fiber-reinforced plastic (1)) so that the orientation of reinforced fibers in the periphery of the optical fiber can be continuously and smoothly changed.
