“…A DC voltage was applied until breakdown occurred and the average value of 5 samples was recorded as the result. As shown in Table 1, the breakdown strength of the CE/EP composite was similar to that measured for the traditional epoxy/glass composite insulations, typically around 50-80 kV/mm [8]. Furthermore, the breakdown strength at 77 K is about 9% higher than that at 300 K.…”

Evaluation of inter-laminar shear strength of GFRP composed of bonded glass/polyimide tapes and cyanateester/epoxy blended resin for ITER TF coils AIP Conference Proceedings 1574, 154 (2014) Abstract. In a Tokamak fusion reactor device like ITER, insulation materials for superconducting magnets are usually fabricated by a vacuum pressure impregnation (VPI) process. Thus these insulation materials must exhibit low viscosity, long working life as well as good radiation resistance. Previous studies have indicated that cyanate ester (CE) blended with epoxy has an excellent resistance against neutron irradiation which is expected to be a candidate insulation material for a fusion magnet. In this work, the rheological behavior of a CE/epoxy (CE/EP) blend containing 40% CE was investigated with non-isothermal and isothermal viscosity experiments. Furthermore, the cryogenic mechanical and electrical properties of the composite were evaluated in terms of interlaminar shear strength and electrical breakdown strength. The results showed that CE/epoxy blend had a very low viscosity and an exceptionally long processing life of about 4 days at 60 o C.

“…As a consequence, it is necessary to investigate the effects of cryogenic temperature and irradiation on the properties of polymer matrix composites so that they can be used with confidence. Up to now, the effects of irradiation on the mechanical properties of various GFRPs have been investigated [7][8][9][10][11][12][13][14][15][16][17]. In addition to the mechanical properties, the thermal characteristics of the material should also be understood.…”

“…In the past decades, extensive work has been done to investigate processing techniques of the insulation materials and the radiation effect on the mechanical properties of GFRP composites at cryogenic temperatures. Based on these studies [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], advanced epoxy based GFRPs with improved mechanical properties and radiation hardness were introduced into fusion technology, and certain chemical structure have been noted to result in enhanced radiation tolerance. In addition, vacuum press impregnation (VPI) are generally selected to fabricate insulation systems.…”
