GWO Blade Repair Training Standard V2.0
2021-04-01_TS_BR_V2
Explain and demonstrate how to calculate the amount of matrix material required for a repair
Define the variables required for calculating the correct amounts of each component of a multi component material given the mixing ratio Explain and demonstrate how to calculate the amount of each component material given a mixing ratio Facilitate practice to improve the participants´ abilities to correctly calculate the total amount of matrix required for a given weight of reinforcement material and the amount of each component in a multicomponent material given the mixing ratio for that material
The participants shall:
Practice the ability to correctly calculate the total amount of matrix required for a given weight of reinforcement material Practice the ability to correctly calculate the amount of each component in a multicomponent material given the mixing ratio for that material
Training staff shall:
Give constructive feedback on the participants´ abilities to correctly calculate the total amount of matrix required for a given weight of reinforcement material and the amount of each component in a multicomponent material given the mixing ratio for that material
CURING AT ELEVATED TEMPERATURES
Learning objective:
The participants can explain how curing at elevated temperature affects the glass transition temperature (TG) and strength of a composite material (Knowledge, intermediate level)
Training staff shall:
Define the term ‘glass transition temperature’
Explain how curing at an elevated temperature will affect the glass transition temperature of the cured material Explain how to find the correct curing temperature for a material from the manufacturer technical data sheet (TDS) Explain that the TDS curing temperature must be cross-checked with the blade manufacturer mixing and curing work instructions Ask the participants relevant questions about how curing at elevated temperature will affect the glass transition temperature (TG) and how the TG will affect the strength of the cured material and explain where to find the correct curing temperatures for a given material
The participants shall:
