为了获得更高的绝缘材料的耐电强度，将聚酰亚胺薄膜结合在两层玻璃纤维胶带增强的环氧树脂之间，形成“三明治”结构的复合胶带，直接包裹在ITER馈线上的高压电势元件上。但由于聚酰亚胺薄膜的投入使用，保温层的结合强度在一定程度上降低了，最终影响了该类型复合材料的层间剪切强度。介绍了玻璃/聚酰亚胺增强环氧树脂层间剪切强度的“预湿”工艺，并在液氮温度下进行了力学试验。这项制造和固化技术，最终需要通过一系列合格测试，然后作为候选选项，将用于工厂的馈线高压部件绝缘，如馈线母线段，和电流引线模型。
To acquire higher dielectric strength of the insulation material, the polyimide films are combined between two layers of glass fiber tape reinforced epoxy resin, and formed into a `sandwich' structure composite tapes which directly wrapped on the ITER Feeder high voltage potential components. But due to the polyimide film brought into use, the bounding strength of the insulation layer is reduced by a certain degree, which finally influences the Interlaminar Shear Strength of this type of composite material. This paper introduces the interlaminar shear strength of the laminate structure insulation manufactured by the glass/polyimide reinforced epoxy resin, with the “prewetted” technology, and the mechanical tests were implemented in liquid nitrogen temperature. This manufacturing and curing technology, need to pass series qualifying tests finally, then as a candidate option, it will be used for Feeder high voltage components insulation in the factory, such as Feeder busbar segments, and current lead mock-ups.
