HONEYCOMB SANDWICH STRUCTURE INCLUDING OPTICAL FIBER SENSOR, AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a honeycomb sandwich structure including an optical fiber sensor, in which an adherend is bonded to a surface with high flatness and the soundness of the adherend and adhesion layer is evaluated with high accuracy.SOLUTION: In a honeycomb sandwich structure where a fiber-reinforced plastic skin material (10) and a honeycomb core (30) are bonded together with an adhesion layer (21), an optical fiber sensor (40) formed with a fiber Bragg grating part (42) whose Bragg wavelength of reflection spectrum changes according to distortion is embedded in the adhesion layer (21) bonding the skin material (10) and honeycomb core (30) together without the occurrence of holes.
