Large Scale Tests of Composite Support Struts for Superconducting Magnetic Energy Storage Rings
Cold-to-warm struts will be used in superconducting magnet energy storage plants to support the superconducting magnet ring. A prototype design of the structural support struts was tested by simulating the in-service, thermal and mechanical, conditions. The maximum strength measured, with the simulated in-service conditions, was 519 MPa (75 ksi). Problems with the design of the end fittings for the struts prohibited determination of the material’s ultimate strength.
