Irradiation effects on a glycidylamine epoxy resin system for insulation in fusion reactor

TGPAP resins were cured using different contents of DDM as the hardener, and were subjected to irradiation in a nuclear fission reactor. The TGPAP/DDM resin systems showed excellent radiation resistance in an integrated neutron flux of 4.71×1022n/m2 (1.77×1022n/m2 with E>0.1MeV) and γ irradiation...

More Information
Summary:TGPAP resins were cured using different contents of DDM as the hardener, and were subjected to irradiation in a nuclear fission reactor. The TGPAP/DDM resin systems showed excellent radiation resistance in an integrated neutron flux of 4.71×1022n/m2 (1.77×1022n/m2 with E>0.1MeV) and γ irradiation dose of 25.9MGy. Hardener contents that affected the crosslinking degree of resins had important effects in irradiation resistance. Positron annihilation lifetime analysis revealed that the size of free-volume holes in the irradiated samples was not changed after neutron irradiation with 1.77×1022n/m2 (E>0.1MeV).
