GWO BR v2.0

GWO Blade Repair Training Standard V2.0

2021-04-01_TS_BR_V2

Ask the participants relevant questions about the reinforcement materials used in composite laminates, and how those materials resist tensile loads in the blade

The participants shall:

Explain in their own words and share understandings about the reinforcement materials used in composite laminates and how those materials resist tensile loads in the blade

Training staff shall:

Give constructive feedback on the par ticipantsā€˜ explanations about the reinforcement materials used in composite laminates, and how those materials resist tensile loads in the blade

MATRIX MATERIALS

Learning objective:

The participants can describe matrix materials used in composite laminates and how the matrix resists compression loads in a blade (Knowledge, basic level)

Training staff shall:

Explain that matrix materials give shape, and distribute and transfer loads on reinforcement by resisting compression loads in blades

Define the terms 'Base resin', 'hardener' and 'accelerator'

Describe the component parts of and at a basic level the chemical reactions that take place during curing in the following materials: Epoxy, polyester vinyl ester and polyurethane

NOTE:

The description of chemical reactions should be kept to a basic level such as when base material and hardener are mixed, they react together causing cross links to form which create a thermo-set plastic material, and during the reaction process, heat is produced.

Describe the differences between the curing process of epoxy materials and polyester materials.

Show examples of typical matrix materials used during blade repair

Ask the participants relevant questions about the matrix materials used in composite laminates and how the matrix resists compression loads in a blade

The participants shall:

Describe in their own words and share their understanding of matrix materials used in composite laminates and how the matrix resists compression loads in a blade
