Blade Repair Standard / V5 02052025
The aim of this lesson is to give the participants the ability to produce a trailing edge section from two sandwich panels, which they will then use to carry out the following repairs as described in later lessons:
1. sandwich repairs with damage extending through both the inner and outer laminates
2.
laminate repairs, which do not affect the core material
3.
surface repairs to gelcoat and paint layers
4.
open trailing edge repairs to both laminates
5.
bond line repairs by adhesive injection
The dimensions of the trailing edge section must be sufficient to allow the participants to carry out the repairs, mentioned above, while challenging them to carry out the repairs with minimal areal limits in order to achieve a sufficient skill level. It is recommended that the trailing edge section measures 500mm along the trailing edge and 600mm parallel to the trailing edge.
The final thickness of the trailing edge, including laminates and bond line, must be no more than 2mm.
The sandwich panels should include an outer laminate consisting of one layer each of triax and biax and an inner laminate consisting of one layer of biax with 10mm core material (e.g. pvc foam or balsa) tapered towards the trailing edge to produce a bond line no wider than 50mm.
After having successfully completed this lesson of the Blade Repair Module, the participants can:
164) Act independently in producing a trailing edge section from two sandwich panels (Ability, intermediate level)
ELEMENT 19.1 - MINIMISE RISKS ASSOCIATED WITH COMPOSITE FIBRE WORK
Learning objective:
165) The participants can act independently in applying the knowledge gained during the general safety lessons to the working environment to minimise the risks associated with composite repair work (Ability, intermediate level)
The instructor shall:
Continually assess and give feedback on the participants’ ability to apply the knowledge gained during the general safety lessons to the working environment to mitigate the risks associated with composite repair work
