Technical training
Blade Repair Standard / V5 23022026
Explain how bent fibres in a laminate will lead to uneven load transfer in the laminate and how this can lead to premature failure of the laminate
Explain how to carefully handle and lay-up dry fibreglass mats to keep the fibres as straight as possible
Ask the participants relevant questions about the consequences of, and how to reduce the possibility of, kinked and bent fibres in a laminate repair
Give constructive feedback on the participants’ explanations about the consequences of, and how to reduce the possibility of, kinked and bent fibres in a laminate repair
The participants shall:
Share their understanding of the consequences of, and how to reduce the possibility of, kinked and bent fibres in a laminate repair
ELEMENT 18.4 - OVERLAPS
Learning objectives:
147) The participants can recognise the terms ‘overlap’ and ‘scarfing’ and the difference between scarfing and overlap (Knowledge, basic level)
148) The participants can recognise that different approaches will be used in different companies’ dependent on company specific procedures (Knowledge, basic level)
149) The participants can explain the importance of overlaps between the repair material and existing material (Knowledge, intermediate level)
The instructor shall:
Define the terms ‘overlap’ and ‘scarfing‘ in the context of blade repair fibre materials
Explain the difference between scarfing and overlap
Emphasise that different approaches will be used in different companies, dependent on company specific procedures
Explain how the strength of the repair depends on each layer of repair fibres overlapping the corresponding layer of existing fibres to ensure the correct load transfer through the repair
Explain that each layer of damaged fibres must be repaired
