Wind Turbine Blade Composites Assessment Using Non-Contact Ultrasound Method

Rozina Steigmann, Nicoleta Iftimie, Adriana Savin, Roman Sturm
Abstract—Wind turbine blades (WTB) are one of the most damageable components of a wind turbine system and due to their importance must be tested during the fabrication and before installing. WTB are produced from composite materials with polymeric matrices, most of the stages of producing are manufacturing and can result in different types of defects. Therefore, non-destructive testing (NDT) techniques that provide surface and internal information of the blade are required. In this paper, ultrasonic testing using noncontact transducers for the control of composites type Glass Fiber Reinforced Plastics (GFRP) with orthophthalic polyester resins matrix is presented in order to prove its capabilities for such applications. The mechanical properties determined by above mentioned method are confirmed by destructive tests using Dynamic Mechanical Analysis.

Index Terms—Wind turbine blade, GFRP, nondestructive testing, non-contact ultrasonic method.
