在4K辐照后，我们测量了ITER环形场线圈候选绝缘系统的剪切和压缩性能。被评估的绝缘体系(适用于真空压力浸渍或预浸渍处理)是环氧树脂、双马来酰亚胺和带有S-2玻璃增强的聚酰亚胺树脂；有些含有云母和聚酰亚胺薄膜屏障。他们暴露在1.8×1022N/m2的快中子注量中。结果表明，剪切强度和弯曲弹性模量对辐照的敏感性大于抗压强度、弹性模量和伸长率。对辐照材料和各种性能的比较为绝缘系统的选择提供了洞察力。
Following irradiation at 4 K, we measured the shear and compressive properties of candidate insulation systems for ITER toroidal field coils. The insulation systems evaluated (suitable for either vacuum-pressure impregnation or preimpregnation processing) were epoxy, bismaleimide, and polyimide resins with S-2-glass reinforcement; some contained mica and polyimide film barriers. They were exposed to a fast neutron fluence of 1.8 × 1022n/m2. Results indicated that the shear strength and flexural modulus are more sensitive to irradiation than the compressive strength, modulus, and elongation. Comparison of irradiated materials and of various properties provides insight for selection of insulation systems.
