In addition to their many advantages, adhesive bonds require more careful process control compared to other methods in order to achieve a strong and reproducible bond. Non-destructive monitoring of curing behavior and hidden adhesive bonds is very labor-intensive. Fiber Bragg Grating (FBG) sensors offer great potential in this area and have proven their worth in recent years due to their immunity to interference and lack of potential. Initial studies using FBG sensors integrated into adhesive joints demonstrate that curing behavior can be monitored using fiber-optic sensors.
This is where the planned research project comes in. The behavior of adhesives (e.g., epoxy resin-, silicone-, and polyurethane-based) and the specific curing behavior within adhesive joints will be investigated in detail experimentally using standard methods such as rheology and fiber-optic sensors. Test setups will also be developed that enable the simultaneous measurement of adhesive properties using standard methods and fiber-optic sensors. The investigations will then lay the foundation for the development of a comparative numerical simulation of adhesive behavior.
