✦ Synopsis

Glass

-fibre-reinforced plastics with 73 ~01% glass content have been developed with improved mechanical and thermal properties in the laminated direction. The thermal contraction down to liquid-helium temperature and the Young's modulus at room temperature in the laminated direction were 0.3% and 23 GPa, respectively. The interlaminar shear strength (ILSS) measured by the short-beam shear method at liquid-nitrogen temperature was confirmed not to decrease with increasing glass content. The change in ILSS induced by electron irradiation was also studied. Approximately a 50% decrease in ILSS was brought about by 20 MGy irradiation. The applicability of the material for large-scale superconducting magnets is discussed.
