摘要

Applications of fiber-reinforced plastic (FRP) composites in modern industries are increasing due to their considerable advantages such as light weight and excellent mechanical properties. Accordingly, importance of operational safety of modern structures made of advanced composites by ensuring the material quality has led to increasing demands for development of non-destructive evaluation (NDE) systems. In the context of a European-project entitled "Validated Inspection Techniques for Composites in Energy Applications" (VITCEA), the aim is to develop and validate traceable procedures for novel NDE techniques with contrasting damage detection capabilities in energy related applications such as wind and marine turbine blades, nacelles, oil and gas flexible risers. As a part of VITCEA, the present study focuses on application of ultrasonic tests (UTs) including conventional, matrix array, immersion and air-coupled, for quantitative defect detection and quality characterization of FRP structures. Results of UTs are subjected to be compared with other NDE approaches which are applicable for inspection of FRPs such as thermography and microwave techniques. Within the present report, the initial results obtained from conventional and immersion UTs are presented and their capabilities as well as limitations are discussed. In order to validate theoretical predictions and simulation results, further experimental tests will be performed in the framework of the project using reference defect artefacts in which the defect sizes and locations are well defined and controlled.
