用于熔体磁体技术的浸渍树脂要求具有辐射稳定性、使用寿命长以及一定程度的韧性，以最大限度地降低冷却过程中破裂的风险。一些与固体芳香胺相结合的多功能树脂在过去被证明在总吸收剂量为200mGy后强度几乎没有损失。使用已知的具有液体芳香胺固化剂的辐射稳定的树脂，评估了添加芳香族环氧树脂作为反应性增韧剂以改善其他脆性树脂的韧性的效果。采用真空浸渍法制备了添加不同增韧剂的无硼玻璃复合材料，并在室温和77K下测试了复合材料的一些关键性能。
Impregnating resins for use in fusion magnet technology are required to be radiation stable, have a long useable life together with some degree of toughness to minimise the risk of cracking during cool‐down. Some multi‐functional resins in combination with solid aromatic amines have, in the past, been shown to have lost little of their strength after a total absorbed dose of 200 MGy. Using resins that are known to be radiation stable with a liquid aromatic amine hardener, the effect of adding an aromatic epoxy resin as a reactive ‘toughening agent,’ to improve the toughness of otherwise brittle resins has been assessed. Boron free glass composites, using various amounts of added toughening agent were prepared by vacuum impregnation and a number of critical composite properties have been measured, at room temperature and at 77 K.
