Technical training
Blade Repair Standard / V4 2023-05-02
The participants shall:
Apply the knowledge gained in Lesson 17 (Lamination Skills) by practising the ability to use a data logger to record and document the ambient temperature and humidity throughout the entire repair process
FILLING AND SHAPING
180 min.
The aim of the lesson is to enable the participants to apply filling safely and effectively.
After having successfully completed this lesson of the Blade Repair Module, the participants can:
260) Take responsibility for applying filling safely and effectively (Ability, intermediate level)
ELEMENT 27.1 - FILLER
Learning objectives:
261) The participants can locate areas in need of filling and apply filler material to gaps/pinholes (Skills, intermediate level) 262) The participants can explain the limitations of using filler in terms of short pot life and layer thickness (Knowledge, intermediate level) 263) The participants can act independently in applying filler with the correct tools to fill pinholes and small defects in the surface of a wind turbine blade (Ability, intermediate level)
The instructor shall:
Describe how pinholes and surface defects degrade the aerodynamic performance of the blade
Explain the limitations of using filler by considering the short pot life of some fillers, and how ambient temperature and humidity can affect the pot life and limitations layer thickness Demonstrate which tools to use and how to apply filler to fill small gaps and pinholes in the surface of a blade while maintaining the correct profile shape of the blade Ask the participants relevant questions about the limitations of using filler in terms of short pot life and layer thickness
