TRAILING EDGE SECTION
Learning objectives:
The participants can explain the differences between a structural and non-structural adhesive (Knowledge, intermediate level) The participants can perform the bonding of two surfaces together to create a trailing edge section (Skills, intermediate level) The participants can act independently in the bonding of two surfaces together to create a trailing edge section (Ability, intermediate level)
Training staff shall:
Explain the differences between a structural and non-structural adhesive and give some examples of products in each category Explain how surface finish and cleanliness will affect the ability of an adhesive to bond to a surface. Explain that the peel ply on a laminate can leave the correct surface finish for adhesive and that the peel ply must only be removed immediately before applying the adhesive Explain that the blade manufacturer’s work instructions detail the surface finish requirements for adhesives Explain and demonstrate where to find the mixing and curing requirements for different adhesive products Demonstrate how to safely cut the sandwich panel in half, and prepare the materials and tools required to bond the pieces together into a trailing edge section
