298) The participants can describe how to inject structural adhesive into the area of debonding and how to verify that it has flowed across the de-bonded area (Knowledge, basic level)
The instructor shall:
Explain the need for caution and the need to follow a blade manufacturer’s work instruction when repairing bond lines that are located above structural parts like the spar or webs of the blade
Demonstrate how to identify the laminate thickness from a blade drawing
Explain:
a. how to drill injection and verification holes through the laminate without damaging the underlying structural parts of the blade
b. how to position the holes so that adhesive can be injected from one side and flow across the area of debonding
c. how to inject structural adhesive into the area of debonding and how to verify that it has flowed across the de-bonded area
d. the limitations of this method in terms of size and quality
Ask the participants relevant questions about:
a. how to drill injection and verification holes through the laminate without damaging the underlying structural parts of the blade
b. how to inject structural adhesive into the area of debonding, and how to verify that it has flowed across the deboned area
The participants shall:
Share their understanding about:
a. how to drill injection and verification holes through the laminate without damaging the underlying structural parts of the blade
b. how to inject structural adhesive into the area of debonding and how to verify that it has flowed across the de-bonded area
