| Zusammenfassung | The results of a study to evaluate the key parameters of the microwave inspection technique for defect detection are presented. Glass fibre-reinforced plastic (GFRP) reference defect artefacts (RDAs), in which defects are simulated artificially to provide well-defined and consistent defect sizes and locations, were used for the experimental investigations. The inspection results are compared to electromagnetic field simulations undertaken using CST Microwave Studio® modelling software. RDAs were designed and manufactured to be representative of the GFRP materials used and the defects typically occurring in diverse energy sector applications (lightweight transport, oil and gas, renewable energy). Defects within the RDAs included artificial delaminations and in-plane fibre misalignment, as well as individual and arrays of back-face drilled holes to represent discrete voids and regions of porosity, respectively. The microwave technique generally showed good detection capability for all defect types, except localised fibre misalignment, and the modelling and experimental results were in excellent agreement. The modelling showed that striations observed in the experimental scans for spatial resolution scans were due to the detection of superposed lateral standing waves within the RDAs. This work was undertaken within EMRP project ENG57 'Validated Inspection Techniques for Composites in Energy Applications (VITCEA)' [1]. |
