Develop and Demonstrate Manufacturing Processes for Fabricating Graphite Filament Reinforced Polyimide (Gr/PI) Composite Structural Elements.
Abstract
One approach for increasing the efficiency of future reusable space vehicles involves the use of lightweight, elevated temperature resistant structural materials. One of the most promising materials for this application is graphite filament reinforced polyimide matrix composites. NASA's project Composites for Advanced Space Transportation Systems (CASTS) has been established to develop and demonstrate the technology required to achieve Gr/PI structural components with 316C (600F) operational capability. The primary objective of this program, which is sponsored under the CASTS Project, is the development and demonstration of fabrication processes for graphite composites based on DuPont's NR-150B2 polyimide which are applicable to fabrication of large size structures. The program involves two major tasks and various sub (a) Material development and characterization for Quality Assurance. (b) Laminate fabrication process development. (c) Adhesive bonding study. (d) Stiffened panel development. (e) Honeycomb panel development. (f) Chopped fiber molding process development. (g) NDI development. (h) Testing for process verification. (i) Specifications. (a) Laminates. (b) Stiffened Panels. (c) Honeycomb Panels. (d) Chopped Fiber Moldings. (e) Structural Component.
