EFFECT OF LOW TEMPERATURE REACTOR IRRADIATION ON ORGANIC INSULATORS IN SUPERCONDUCTING MAGNETS.

[In Japanese. / En japonais.]

Type of article: Article

Summary

FLEXURAL AND IMPACT TESTS ARE CARRIED OUT AT 4.2 K WITHOUT WARMUP AFTER LOW TEMPERATURE IRRADIATION FOR SEVERAL FIBER REINFORCED PLASTICS. AFTER IRRADIATION OF 1.1 MILLION RAD, THE REDUCTION IN FLEXURAL STRENGTH OF G-10 CR IS ABOUT 70% AND THAT OF G-11 CR ABOUT 25%. THERE IS NO CHANGE FOR GLASS FIBER REINFORCED POLYAMIDE. OTHER KINDS OF GLASS FIBER REINFORCED EPOXIES SHOW A REDUCTION IN STRENGTH BUT THE FLEXURAL STRENGTH OF CARBON FIBER REINFORCED EPOXIES INCREASES A LITTLE BY IRRADIATION.
