Effect of low temperature reactor irradiation on organic insulators in superconducting magnets
Abstract
Specimens of organic materials were subjected to tensile and compression tests in liquid nitrogen after fission reactor irradiation at 5 K. The results indicate that polypropylene, polycarbonate, and polyester have low radiation resistance due to chain fracture and are too brittle to permit mechanical testing. For epoxy resins the stress-strain curves after irradiation are strongly dependent on the kind of hardener. The strength of epoxy resins hardened by polyamide shows a substantial decrease after low temperature irradiation.
