As part of the NASA sponsored Advanced Composite Technology program, Lockheed is developing woven and braided carbon fiber preforms for primary structural applications in transport airplane fuselage structures. The objective of this program is to develop composite primary structures that show significant weight saving compared to current metal transports and with a 20 to 25 percent reduction in acquisition cost. Both 2-D and 3-D braided frame preforms have been designed and fabricated. These preforms were resin transfer molded (RTM) and tested. Preforms using epoxy powder coated tows have been designed, fabricated and tested for fuselage window belt and side panel applications. These structures were designed to the Boeing 767X loads and criteria. Textile window-belt preforms will be supplied to Boeing for inclusion in large test panels with tow placed skins.
