Blade Repair Standard / V5 02052025
Practise the ability to adjust the temperature of a heating blanket according to the readings from the thermocouple to the correct curing temperature for the matrix material used, and to control and record the curing temperature throughout the entire curing process
Practise the ability to record the ambient temperature and humidity throughout the entire process of building and curing a sandwich panel
After the curing time, practise the ability to safely remove and dispose of the vacuum consumables except for the peel ply
ELEMENT 19.5 - TRAILING EDGE SECTION
Learning objectives:
174) The participants can explain the differences between a structural and non-structural adhesive (Knowledge, intermediate level)
175) The participants can perform the bonding of two surfaces together to create a trailing edge section (Skills, intermediate level)
176) The participants can act independently in the bonding of two surfaces together to create a trailing edge section (Ability, intermediate level)
The instructor 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
Demonstrate how to apply the adhesive to the bond line to ensure the correct dimension, and how to correctly apply clamps to the bond line to ensure that the adhesive wets out the two surfaces
