While in the 1970's and 1980's, composites were adopted for aerospace structure for increased performance and weight savings, the 1990's and 2000's witnessed the attention towards cost-effective fabrication. All thermoset processes that utilize such machines rely on autoclaves to consolidate the laminates, at significant acquisition and operational expense. Autoclaves to consolidate wings are hugely expensive. Autoclaves for fuselages are nearly cost-prohibitive (only one exists). Autoclaves for the Ares V do not exist. The marketplace would welcome a proven out-of-autoclave fabrication technology.
