Give constructive feedback on the participants’ application of the knowledge gained in lesson 16 (lamination skills) by practicing 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, the participants will be able to:

Take responsibility for applying filling safely and effectively (Ability, intermediate level)

FILLER

Learning objectives:

The participants can locate areas in need of filling and apply filler material to gaps/pinholes (Skills, intermediate level) The participants can explain the limitations of using filler in terms of short pot life and layer thickness (Knowledge, intermediate level) 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)

Training staff 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 Facilitate practice to improve the participants’ ability to apply filler with the correct tools to fill pinholes and small defects in the surface of a wind turbine blade

The participants shall:

Explain in their own words and share their understanding of the limitations of using filler in terms of short pot life and layer thickness Practice the ability to apply filler with the correct tools to fill pinholes and small defects in the surface of a wind turbine blade

Training staff shall:
