Blade Repair Standard / V4 2023-05-02
Explain why this is important in terms of wind turbine blades by considering the loads on a blade, the structural requirements of the blade, and the implications for transport and lifting operations Ask the participants relevant questions about common materials used for core material, and the function of the inner and outer laminates and the core material in a sandwich construction, and the reasons for using a sandwich construction in wind turbine blades Give constructive feedback on the participants’ explanations about the function of the inner and outer laminates and the core material in a sandwich construction, and the reasons for using a sandwich construction in wind turbine blades
The participants shall:
Describe in their own words and share their understanding of common materials used for core material
Share their understanding of:
a. the function of the inner and outer laminates and the core material in a sandwich construction
b. the reasons for using a sandwich construction in wind turbine blades
ELEMENT 19.3 - CURING OF FIBRE REINFORCED COMPOSITE LAMINATE
Learning objectives:
169) The participants can explain the functions of the tools, instruments and vacuum consumables used during the curing process (Knowledge, intermediate level) 170) The participants can perform the curing of a fibre-reinforced composite laminate using heat and vacuum and record the vacuum level and temperature (Skills, intermediate level) 171) The participants can act independently in performing curing of a fibre reinforced composite laminate using heat and vacuum, and record the vacuum level and temperature (Ability, intermediate level)
The instructor shall:
Explain the function of the tools required to cure a laminate with heat and vacuum, and the instruments required to record the vacuum level and curing temperature Explain the health and safety risks associated with using heating blankets and vacuum pumps by considering the risk of burns, the risk of fire and electrical hazards Demonstrate how to mitigate the above described risks using PPE, pre-use inspections, correct handling of the blankets, and the use of electrical safety devices such as residual current devices
