GWO Blade Repair Training Standard V2.0
2021-04-01_TS_BR_V2
Engage in a group discussion about typical blade faults, damages, possible causes and the subsequent performance implications Engage in a group discussion on the role of listed mitigations (a-f) in element 13.5.2 in reducing blade damage
Training staff shall:
Give constructive feedback on the participants’ group discussions about typical blade faults, damages, causes, implications and mitigations
MATERIALS
75 min.
The aim of the lesson is to enable the participants to distinguish between the various materials, and understand the differences in characteristics and application of the material types when working with inspection and repair in a safe and efficient manner.
After successfully having completed this lesson, the participants will be able to:
Distinguish between the various materials (Skills, intermediate level)
Explain the differences in characteristics and application of the material types when working with inspection and repair (Knowledge, intermediate level)
REINFORCEMENT MATERIALS
Learning objective:
The participants can explain the reinforcement materials used in composite laminates and how those materials resist tensile loads in the blade (Knowledge, intermediate level)
Training staff shall:
Explain that reinforcement materials give strength to the composite by resisting tensile loads in a laminate structure Describe the different types of reinforcement materials used in blade production (glass fibre and carbon fibre)
Define the terms 'UD', 'Biax' and 'Triax' in relation to reinforcement materials
Show examples of and explain the characteristics of UD, Biax and Triax glass fibre mats
Explain how a laminate is constructed from multiple layers of fibres
Show an example of and explain the characteristics of 'hardback' materials
Define the term 'prepreg'
Explain how prepreg materials are used during production
