Autoclave Composite Molding for Stronger and Denser Materials . by dewi susanti. Autoclave composite molding has long been used in the aerospace industry. This specialized fabrication technique produces materials that display greater strength and higher density and hence, fit the bill as construction material for aircrafts, missiles and spacecrafts.
An inert gas (like Nitrogen) is then introduced in the autoclave to eliminate oxidation. (Oxidation aids polymer degradation and hence you need to eliminate them). Gases are normally poor conductors of heat and thus increases the curing time. You may also come across this process referred to as "gas curing
