Blade Repair Standard / V5 02052025
102) Explain the differences in characteristics and application of the material types when working with inspection and repair (Knowledge, intermediate level)
ELEMENT 14.1 - REINFORCEMENT MATERIALS
Learning objective:
103) The participants can explain the reinforcement materials used in composite laminates and how those materials resist tensile loads in the blade (Knowledge, intermediate level)
The instructor shall:
Explain that reinforcement materials give strength to the composite by resisting tensile loads in a laminate structure
Describe the different types of reinforcement materials used in blade production (glass fibre and carbon fibre)
Define the terms 'UD', 'Biax' and 'Triax' in relation to reinforcement materials
Show examples of, and explain the characteristics of, UD, Biax and Triax glass fibre mats
Explain how a laminate is constructed from multiple layers of fibres
Show an example of, and explain the characteristics of, 'hardback' materials
Define the term 'prepreg'
Explain how prepreg materials are used during production
Ask the participants relevant questions about the reinforcement materials used in composite laminates, and how those materials resist tensile loads in the blade
Give constructive feedback on the participants‘ explanations about the reinforcement materials used in composite laminates, and how those materials resist tensile loads in the blade
The participants shall:
Share understandings about the reinforcement materials used in composite laminates and how those materials resist tensile loads in the blade
