Hello guys I am new here. Congrats to all of you for the great work.I am using carbon fiber pre-preg that cures for 2 hours at 175 degrees . Is it possible to cure at 50 degrees for much more time ?

sounds like you are trying to use an aerospace resin system prepreg if its that elevated temp, you might be able to cure at a lower temp but as above the surface finish wont be that nice and the properties of it wont be great as it will come out more like cardboard than a nice laminate.

You can get tooling prepregs that cure from 50degrees upwards and then postcure at 180degrees if thats what you are needing for your application?
