Demoulding of prepreg part at 100°C

Hello, 
I have one question, please. Is there any danger in terms of deformation of a cured prepreg part, if I will do demoulding before the part and mould reach the room temperature? I mean, for example, if I pull the part out of the mould while the mould temperature is still approx. 100°C (curing at 120°C). For more info, I use prepreg carbon from EasyComposites and use a aluminium mould. Thank you for your help!

I release 100C hot pre preg parts all the time with no issue.
