Curing it under heat and pressure in an autoclave consolidates the laminate and drives out trapped air that would otherwise show as flaws in the finished surface. Other processes introduce the resin at the mold, so the ratio is set during layup rather than before it.\u003c\/p\u003e\n\u003cp\u003eA duct fin is a thin, deep, sharply folded shape — the geometry most likely to show print-through or a resin-rich edge when it's laid by hand.
