ZFRP's bobbins that consist of particular fiber's winding tension expand to the direction of the circumference at the time of cooling. The superconducting coils' operation temperature is cryogenic temperature. Consequently, when ZFRP's bobbins are used of superconducting coil's bobbins, those bobbins expand to the direction of the circumference. Because the expansion constrains superconducting wire's mechanical disturbance by electromagnetic force, the quench current of superconducting coil's wire is stabilized, In this paper, we measured the quench current of superconducting coil using ZFRP's bobbins and GFRP's bobbins which were the general material used for cryogenic temperature. And the effect of improvement of superconducting coil's stability by ZFRP's bobbins was investigated by weighing those measurement results of each coil's quench current.
