Abstract

Mechanical properties of zirconia and silica have been measured at cryogenic temperatures. To answer the demands for structural and/or insulation materials in a large scaled superconducting magnet, the ceramic materials were examined. Mechanical properties of certain ceramics such as zirconia, were confirmed to increase at cryogenic temperatures compared with those at room temperatures. Although silica has been widely used as the reinforcement of glass fiber reinforced plastics(GFRP)m the mechanical properties of bulk at cryogenic temperatures have not been clarified. The purpose of this study is to reveal the mechanical properties of those ceramics and to investigate the improving mechanisms of mechanical properties at cryogenic temperature.
