I'm wondering if I can use a cured foam as a male tool surface onto which I can laminate and then envelope vac bag.
My ideal material of choice would be
1) moderate -high density for compressive strength under vac bag vacuum conditions,
2) easily removed by either dissolving (or the very least chipping and hacking away at it... pita...)
3) can withstand elevated cure temps up to 120C
PU vs Epoxy foam:
Anyone have practical experience with cutting either PU foam or Epoxy foam? Which is easier?
The higher densitiy versions of pourable expanding foam are said to be decent structural surfaces and also allow machining. So does that confer the same thing as compressive strength for example under vacuum?
I would need the foam to be dimensionally stable at eleveated temperatures. |
