{"_id":"2003","abstract":[{"lang":"eng","text":"On-site aircraft repairs are gaining in importance due to the susceptibility of carbon fibre reinforced polymers to damage. Repairs themselves are required to be inspected for quality, preferably cost- and time-efficiently. This paper presents an approach for the inspection of repaired composites based on guided Lamb waves. The focus is on cost-effective signal excitation and effective signal processing. Lamb waves are excited with piezoelectric transducers at the resonance frequency of the material under test. Measured signals are processed with a complex wavelet transform to improve damage detection. The proposed approach is evaluated on two test specimens, one of which has a defect in the adhesive bond."}],"date_updated":"2023-03-15T13:49:38Z","place":"Zaragoza, Spain","title":"Lamb Wave-based Quality Inspection of Repaired Carbon Fibre Reinforced Polymers for On-Site Aircraft Maintenance","date_created":"2019-11-22T12:54:24Z","year":2019,"citation":{"chicago":"Holst, Christoph-Alexander, Kristian Röckemann, Andreas Steinmetz, and Volker Lohweg. “Lamb Wave-Based Quality Inspection of Repaired Carbon Fibre Reinforced Polymers for On-Site Aircraft Maintenance.” In <i>24nd IEEE International Conference on Emerging Technologies and Factory Automation (ETFA2019)</i>.
