GWO Blade Repair Training Standard V2.0
2021-04-01_TS_BR_V2
The participants can recognise how a composite laminate structure is built up of multiple layers of reinforcement material (Knowledge, basic level) The participants can recognise how each layer of reinforcement material resists tensile loads in a specific direction (Knowledge, basic level) The participants can discuss the importance of fibre orientation in a laminate structure (Knowledge, intermediate level)
Training staff shall:
Explain how a composite laminate structure is built up of multiple layers of reinforcement material
Explain how each layer of reinforcement material resists tensile loads in a specific direction
Facilitate group discussions about the importance of aligning repair fibres with the existing fibres in each layer that is being repaired
The participants shall:
Engage in a group discussion and share their understanding of the importance of aligning the repair fibres in the direction of the fibres in each layer of the existing fibres in the context of tensile load transfer through the repair
Training staff shall:
Give constructive feedback on the participants’ understanding of the importance of aligning the repair fibres in the direction of the fibres in each layer of the existing fibres in the context of tensile load transfer through the repair
KINKED OR BENT FIBRES
Learning objective:
The participants can explain the consequences of kinked or bent fibres in a laminate structure (Knowledge, intermediate level)
Training staff shall:
Show an example and explain how easily glass fibres will break if they are kinked
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
The participants shall:
Explain in their own words and share their understanding of the consequences of and how to reduce the possibility of kinked and bent fibres in a laminate repair
