Proper curing and surface finishing minimize print-through effects.
Minor; engineers account for it during layup.
Quality foams have very low compression under vacuum pressure.
Yes. Multi-density configurations optimize weight and strength.
Not always, but vacuum bagging improves bonding.
160–250 kg/m³ for compression strength.
60–100 kg/m³, depending on span and load.
Typically 80–130 kg/m³ for slamming areas.
Often yes, due to easier processing and better impact
