Just another issue I´m unsuccesfull.
Trying to laminate a sandwich panel  with nonconstant thickness in 2 steps process. 1st step there is a cca 0.7mm thick panel based on UD carbon prepregs - 1x54+2x100+2x200gsm UD. On 2nd step apply the Rohacell core and inner skin based on twill 200gsm carbon prepreg, see the attchd. sketch. The curing process starts on vac-1bar@100°C for 4.5hours, cooling slow down to 30°C for 6hours. After demoulding the panel is going to distorsion about 10mm.
Any tips for process changes?
Thanks a lot, Rosta
