Popular science description

English

The use of composite materials has increased in manufacturing of large structures. These structures can be subjected to different types of defects, for which detection has always been a challenge. Wind turbine blades are a perfect example of these large structures that can be exposed to different defects such as delamination, debonding or ice accumulation during the turbine operation. Tools based on ultrasonic guided waves can be used for health monitoring of such structures. The special characteristics of guided wave-based tools such as mobility, rapidity and cost efficiency make them interesting to be used for non-destructive testing and structural health monitoring. This work focuses on investigating the applications of ultrasonic guided waves to defect and ice detection on composite materials. The methodology is based on computer simulations of wave propagation in large composite structures as well as experimental work on different defect and ice detection scenarios. The developed methods have the potential to be used to design multifunctional intelligent detection systems for wind turbines.
