What resin system? I think I have just copied what happens when non post cured carbon is left out in the sun, it sags as it post cures. I twisted the carbon, held it in place and heated it with a hot air gun to around 130deg C for 10 minutes then let it cool overnight. Not sure what the HDT is as it isn't stated on the data sheet: https://shdcomposites.com/admin/resources/mtc510-tds.pdf

However, this was going to be used to adjust a door shut line so that wouldn't be an issue.
