Adhesively bonded joints have been attracting attention as a method of joining structural components such as automobiles. When adhesive bonding is used to join structural components, it is important to ensure the long-term reliability of the bonded joints, as they may degrade over time and lose their mechanical strength. In this study, a method to quantitatively evaluate the residual strength of degraded cured adhesives was investigated using spectroscopic analysis.
