Resumo

A novel epoxy resin system based on a low viscosity Bisphenol-A (DGEBA)/Bisphenol-F (DGEBF) blend has been investigated for use in tight-wound superconducting magnet impregnation. The principle is to decrease the Bisphenol-A resin system viscosity by adding the low viscosity Bisphenol-F resin. The rheological and mechanical properties of the blend system are compared to the pure Bisphenol-A resin and also to the Bisphenol-F resin both cured with acid anhydride. For the vacuum/pressure impregnation, both the pure Bisphenol-F resin system and DGEBA/DGEBF blend system can be applied without S-glass fabric between coil layers due to its higher rigidity at low temperature and good resistance to thermal shock. This resin system have been tested for impregnation of copper and NbTi wire wound coils whilst Bisphenol-A resin system have been used for testing Nb3Sn coil impregnation where S-glass braid is present as wire insulation.
