abstract = "This paper presents Non-Destructive Testing (NDT) techniques for detecting thermal degradation of the polymer matrix and silicone based release agent residues on Carbon Fiber Reinforced Plastic (CFRP) surfaces. Thermal degradation can be successfully determined by mobile Fourier Transform Infrared spectroscopy (FTIR). The presence of oxygen during thermal degradation strongly influences the chemical changes of the matrix and therefore different degradation scenarios are investigated. For a differentiation of the multiple scenarios a Partial Least Squares Discriminant Analysis (PLS-DA) algorithm is used. Mobile X-Ray Fluorescence spectroscopy (XRF) is successfully applied to determine residues of silicone based release agents on the CFRP surface, which lead to problems for adhesive bonding or coating. Additionally, a novel approach is investigated by combining a laser treatment of the surface with an analysis of the evaporated gas phase by a Gas Chromatograph coupled to an Ion Mobility Spectrometer (GC-IMS).",
