Hi, can we use  POP as mold material for CFRP prepreg component??
maximum temperature for curing-120 degree

HI
I did use plaster of Paris in 2012 to create a prototype like other do with modelling clay and found plaster easier to sculpture
once completely dry I coated it with wood hardener/cellulouse  to consolidate the surface, sprayed it with 2k epoxy high-build filler and then 2k car paint
But I doubt that plaster would work as mould material

From that with using wax and PVA i created  final mould still in use today :-)
