Out-of-Autoclave (OOA), Vacuum Bag Only (VBO) and - 'Not-in-the-Autoclave'

摘要

During the recent conference events, the topic of numerous technical papers has been titled as OOA or VBO-"Out-of-Autoclave" and "Vacuum Bag Only". Although the terms have been used more frequently on paper titles, and in panel sessions, mostly within the last 4-6 years, the technology has been advancing for the past 15 years or so. The technologies associated with pre-impregnated ("prepreg") materials used in non-autoclave pressure systems and processes, have gained momentum since many "tooling" materials started being used for making prototype structures.
