Blade Repair Standard / V4 2023-05-02
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 Give constructive feedback on the participants’ explanations about how curing at elevated temperature will affect the glass transition temperature (TG). In addition, 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:
Share their understanding of:
a. how curing at elevated temperature will affect the glass transition temperature (TG)
b. how the TG will affect the strength of the cured material, and explain where to find the correct curing temperatures for a given material
ELEMENT 17.8 - ASCERTAINING CORRECT CURING
Learning objectives:
152) The participants can apply a Barcol and / or a Shore D hardness tester (Skills, Intermediate level)
153) The participants can recognise that curing control methods can vary between resin systems (Knowledge, basic level) 154) The participants can act independently in applying a Barcol/ Shore D hardness tester to ascertain that the matrix material has correctly cured in accordance with the material technical data sheet or the blade manufacturer ’s work instruction (Ability, intermediate level)
The instructor shall:
Demonstrate how to find the correct cured hardness values for a laminate from the material technical data sheet and from the blade manufacturer work instruction
Demonstrate how to use a Barcol and/or a Shore D hardness tester to test the hardness of a cured laminate
Highlight that curing control methods can vary between resin systems
Explain how to collect a sample of laminate for testing in a laboratory
Facilitate practice to improve the participants’ ability to use a Barcol and/or a Shore D hardness tester to ascertain whether a laminate has cured correctly in accordance with the material technical data sheet or the blade manufacturer’s work instruction
