GWO Blade Repair Training Standard V2.0
2021-04-01_TS_BR_V2
Explain how the TDS must be cross referenced with a blade manufacturer specific work instruction relating to mixing and curing materials Explain how care must be taken to ensure that the correct mixing ratio is used, as these are given in the TDS by weight and volume Explain how incorrect mixing ratios will affect the cured product, with a focus on the implications to health and safety of sanding in unreacted materials Explain why it is important to calculate the mixing ratio for each batch of chemicals that is being mixed
Ask the participants relevant questions about:
a. the term ‘mixing ratio’
b. how the incorrect mixing ratio of a multi component material will affect the properties of the cured material
c. where to find the mixing ratio for a given material
d. the chemical reaction between the base resin and hardener in epoxy, polyester and polyurethane materials
The participants shall:
Explain in their own words and share their understanding of the term ‘mixing ratio’
Explain in their own words and share their understanding of how the incorrect mixing ratio of a multicomponent material will affect the properties of the cured material Explain in their own words and share their understanding of where to find the mixing ratio for a given material Describe in their own words and share their understanding of the chemical reaction between the base resin and hardener in epoxy, polyester and polyurethane materials
Training staff shall:
Give constructive feedback on the participants’ explanations about the term ‘mixing ratio’, how the incorrect mixing ratio of a multicomponent material will affect the properties of the cured material, and where to find the mixing ratio for a given material
CALCULATION OF MATRIX MATERIAL
Learning objective:
The participants can perform calculations of the amount of matrix material and the ratio of resin to hardener required for a given weight of reinforcement material (Skills, intermediate level)
Training staff shall:
Define the variables required for calculating the amount of matrix material required for a given weight of reinforcement material
