Construction of high-temperature superconducting magnets typically involves impregnation of a coil in a liquid medium, such as epoxy, which is then solidified. This impregnation provides mechanical integrity to the magnet and facilitates heat transfer. The choice of material used for impregnation requires careful consideration of the material properties and the performance requirements in order to ensure optimal magnet operation. This paper offers a comprehensive educational resource on this topic, reviewing the literature available on materials for magnet impregnation. A detailed explanation of considerations for selecting an impregnation material are presented, along with a review of several types of materials and their characteristics as reported in the literature. The materials are compared, and their suitability to different applications is discussed. Topics for future research are suggested.

Unlike most fiber-reinforced polymer composites, the measured interlaminar fracture energy of the glass-polyester Extren is significantly greater at 77 K than at room temperature (298 K). Composite microfailure is adhesive at room temperature but cohesive at 77 K. SEM and acoustic emission results suggest the enhanced interlaminar fracture toughness at 77 K is associated with increased matrix cracking which occurs at cryogenic conditions. The additional fracture surfaces increase the amount of released surface energy.
