Fiber Composite Retaining Rings for Turbine-Driven Generators Volume 2:Composite Retaining Ring Fabrication Studies

摘要

This Abstract, which is for Volume 2 of a four volume final report, describes the activities leading to the successful fabrication of thick wall graphite fiber reinforced spin test rings. These spin test rings were designed and produced in order to define construction, material and manufacturing concepts necessary for the application of composite retaining rings to future full size generator rotors. Baseline composite material and prototype ring test data were established. This led to the selection of the AS-4/3501 -6 (Graphite Fiber/Epoxy) material for spin test ring fabrication. Manufacturing and cost analysis studies identified a new method for fabricating these rings. This method, the Bias Ply Winding Process, resulted in high quality rings meeting all specification and spin test requirements. Physical property and friction coefficient data were collected on the spin test rings. This information was used to clarify the retaining ring attachment concepts defined in this program.
