| Résumé : |
Use of non-autoclave manufacturing technology has been limited by processes which provide lower quality than autoclave cured approaches and materials which do not meet the properties or structural life demanded. Non-Autoclave Manufacturing Technology is a program jointly accomplished by a Boeing-led team and the US Gouvernment (DARPA) under the guidance of the Air Force to address the challenges to enable disruptive, persuasive use of vacuum-bag-only prepreg for reduced recurring cost and cycle time for primary structures. The program addresses the following:
- Autoclave-like properties with an initial cure temperature of 93°C with vacuum only and free standing post cure at 177°C
- Reduced cost/span time tooling family for use in 10-25 units
- Processing and tooling to match production, besause the tooling concepts are also production-worthy
One key to achieving these goals is a 121°C use, medium tough epoxy prepreg system, representing a third generation of prepreg processed under vacuum pressure only. This article summarizes progress during the first year of the program. |
