Abstract

In this study the bonding quality evaluation of FRP honeycomb structure was performed by the ultrasonic C-Scan method and stress wave factor measurements. These NDT techniques could be well applied to the disbonding detection of FRP honeycomb structures. Especially, stress wave factor (SWF) measurement is expected to be a useful technique in field applications.
