### P2.9.32 Surface and subsurface FTIR-spectroscopic detection of critical parameters for adhesive bonding of CFRP

Roland Galos & Jürgen Kasberger
The presented work deals with preliminary investigations of contamination conditions prior the bonding procedure of carbon-fiber-reinforced polymer (CFRP) structures. As identified by airplane manufacturers, the monitoring of thermal damages and different contamination scenarios like moisture uptake and release agent and oil residues is required before bonding of CFRP. Here we are using FTIR-spectroscopic measurement systems in the mid infrared (MIR) wavelength region to monitor characteristic spectral features. In order to achieve the goal of monitoring...
