Description
Summary:Carbon Fiber reinforced polymer (CFRP) bonding is a paramount asset for enabling the transition towards a green aircraft based transport industry. Guaranteeing the quality of the bonding is crucial for ensuring its strength and its robustness to mechanical stresses. Here, we present the results of an Ion Mobility Spectrometer based no-contact methodology to detect the presence of two contaminants that are usually present on surfaces before bonding. False negative rate was found to be less than 5% at an accuracy level of 92% for detection which look promising for further development aiming at field deployment.
