Abstract

Carbon fiber sheet surface adhesion method is a well-known repair and reinforcement method for concrete structures like bridges and buildings. The method has high tensile strength and durability. However, the attached sheet is easy to detached from the structure during and after the construction because of the method’s labor intensive characteristics. An accurate measurement and evaluation system of damage location needed to identify the type of damages. In this study, a conceptual design of fiber optic sensor embedded carbon fiber sheet was developed to track the measured signal by deflection of the samples using BOTDR. After the analysis of the measured value, it verifies the applicability of the optical fiber embedded carbon fiber sheet to check the state of a reinforced structure.
