Advanced Fiber Reinforced Thermoplastic Structures
Abstract
The objective of the program was to demonstrate the performance and cost savings of graphite/polysulfone. This objective was attained through a thirteen task program which cultimated in the design, fabrication and test of a full scale elevator torque box. The P-1700 polysulfone resin was selected and used with A-S unidirectional graphite fibers (Hercules 3004/A-S/P1700 prepreg) and with T-300 woven graphite fibers (Hexcel T-3004/23x24, 811 Satin Prepreg). Tooling concepts, consolidation and post forming processes, and field repair procedures were developed. The graphite/thermoplastic elevator had a 27% weight savings as compared to the aluminum elevator, and a cost saving of 20%, by the tenth elevator shipset. A limited study of a Union Carbide proprietary thermoplastic, known as PKXA, which has much improved solvent resistance as compared to P-1700 polysulfone, was conducted. This limited study showed that PKXA appeared to be a viable substitute for P-1700 polysulfone. It is recommended that a further study of PKXA be made in order to further optimize the manufacturing procedures for it.
