Using vacuum-bag-only (VBO) for atmospheric pressures, the new OOA processes promise to deliver less than 1 percent void content required for aerospace primary structures.  Led by material scientists at [[Air Force Research Lab]], the technique would save the costs of constructing and installing large structure autoclaves ($100M saved at NASA) and making small production runs of 100 aircraft economically viable.<ref>{{cite web|url=http://www.compositesworld.com/articles/out-of-autoclave-prepregs-hype-or-revolution |title=Out-of-autoclave prepregs: Hype or revolution? |publisher=Composites World |date= |access-date=2011-01-03}}</ref>
