Abstract
Based on bisphenol-F epoxy resin, we have been studying the chemorheological and mechanical properties of epoxy resin systems composed by two components: diglycidil ether of bisphenol-F (DGEBF) and aliphatic diamine as curing agent, aiming its use for superconducting magnet impregnation. Another formulations with diglycidil ether of bisphenol-A (DGEBA) unmodified resin are studied as well and their properties compared with the two component system ones. The DGBEF flexible resin system has shown low viscosity, good thermal shock resistance, low glass transition temperature (Tg ≈ 30°C) and low mechanical strength at room temperature. Viscosity and temperature versus time curves have shown the curing evolution and they are associated with the reaction activation process. The DGEBF resin system shows high flexibility at room temperature; the Young’s modulus and viscosity are lower than the DGEBA resin system. The DGEBF resin system has a potential use for impregnation of tightly wound coils where low viscosity is an important fabrication issue.
