Testing of Fiberglass-Reinforced Polyester Composite

The Wisconsin superconductive energy storage magnet requires a large, low-thermal-conductive, high-load-carrying, supporting structure to carry the radial and axial compressive loads from 1.8-K magnet coils to room temperature bedrock. For economic reasons, fiberglass-polyester composite (Extren, with glass content of 44%, manufactured by Morrison Molded Fiberglass) was chosen over fiberglassepoxy composite.
