Low temperature properties of potting and structural materials for superconducting magnets

The embedding of superconductors is one component determining the behavior, such as training charcteristics or degradation, of superconducting coil assemblies. Mechanical, thermomechanical and electrical properties of potting or structural materials are discussed. A review of low temperature measurements of parameters, such as elastic moduli, work of fracture, thermal contraction and conductivity, specific heat and breakdown voltage on unfilled, filled or reinforced epoxy resins is given.
