Repairing method, repairing structure and connecting structure of embedded optical fiber of composite material structure

摘要

A method of repairing an embedded optical fiber (10) of a composite material structure (1) including an embedded optical fiber embedded in a composite material, includes removing a portion of the composite material including a damaged portion of the embedded optical fiber (10) to form an opening portion (3); polishing an end surface of the embedded optical fiber (10) exposed in the opening portion (3) and an end surface of the composite material exposed in the opening portion; and performing position adjustment such that a core of the polished embedded optical fiber and a core of a replacement optical fiber are aligned with each other, butting the end surface of the embedded optical fiber and an end surface of the replacement optical fiber with each other, and connecting the end surface of the embedded optical fiber and the end surface of the replacement optical fiber together.
