在环氧树脂体系中提供辐射稳定性所必需的结构特征是公认的。然而，通常，辐射稳定的树脂体系是高粘性的，并且不适合于真空浸渍或“湿缠绕”应用。在过去，对电离辐射稳定的树脂的使用仅限于可以使用预浸渍纤维和织物的那些应用。对化学结构与辐射稳定性之间关系的理解，使人们能够确定新的材料，这些材料可以预见地抵抗电离辐射。本文介绍了一些树脂体系的结构和工艺特性，这些树脂体系具有长使用寿命、低粘度和一系列性能，使它们适合于真空浸渍磁体线圈和其他结构，或用于“湿绕组”应用。本文报道了树脂和复合材料在低至77K的温度下的物理和机械性能。
The structural features that are necessary to provide radiation stability in epoxide resin systems are well established. However, in general, radiation stable resin systems are highly viscous and are not suitable for vacuum impregnation or “wet winding” applications. In the past, the use of resins that are stable to ionising radiation has been limited to those applications where pre-impregnated fibres and fabrics can be used. The understanding of the relationship of chemical structure to radiation stability, has enabled new materials to be identified that may, predictably, be resistant to ionising radiation. This paper describes the structure and processing characteristics of a number of resin systems that have long useable life, low viscosity and a range of properties that render them suitable for vacuum impregnation of magnet coils and other structures, or for “wet winding” applications. The paper reports the physical and mechanical properties of resins and composites at temperatures down to 77K.
