GWO Blade Repair Training Standard V2.0
2021-04-01_TS_BR_V2
Training staff shall:
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
OVERLAPS
Learning objectives:
The participants can recognise the terms ‘overlap’ and ‘ scarfing ’ and the difference between scarfing and overlap (Knowledge, basic level) The participants can recognise that different approaches will be used in different companies’ dependent on company specific procedures (Knowledge, basic level) The participants can explain the importance of overlaps between the repair material and existing material (Knowledge, intermediate level)
Training staff 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
Ask the participants relevant questions about the importance of maintaining the correct overlaps between each repair layer and the corresponding existing layer in the damaged composite laminate
The participants shall:
Explain in their own words and share their understanding of the importance of maintaining the correct overlaps between each repair layer and the corresponding existing layer in the damaged composite laminate
Training staff shall:
Give constructive feedback on the participants’ explanations about the importance of maintaining the correct overlaps between each repair layer and the corresponding existing layer in the damaged composite laminate
DRY FIBRES AND AIR VOIDS
Learning objective:
The participants can explain the effect of dry fibres and air voids on the strength of a laminate structure (Knowledge, intermediate level)
