Webb9 jan. 2024 · For foam or balsa on contoured surfaces, bagging the core is a great idea even if the skins are open molded with only manual consolidation – aka. rolling and bubble-popping. So if you are only going to bag one thing – make it the core to the mold-side skin. For production purposes, infusion is usually a better and more consistent choice. Webb1 aug. 2010 · The process of forming the foam was developed at Oak Ridge National Laboratory in the Carbon and Insulation Materials Technology Group [1].This process begins with a mesophase pitch (coal, petroleum, or hydrocarbons may also be used) precursor which is placed in a pressure vessel and subjected to a carbonization process …
