Radiation resistance of epoxy systems: I. Effect of epoxy resin structure

A series of epoxy resins have been formulated for use at cryogenic temperatures and more specifically for superconducting magnets. The radiation resistance of these materials will be critical for some applications and thus the purpose of this report is to describe the thermal, physical and mechanical properties of a series of epoxy formulations as a function of total radiation dose using a 60C source. The properties are measured both at cryogenic and ambient conditions. A diglycidyl ether of bisphenol A monomer is coreacted with a series of aliphatic diamines and contrasted with the same formulation using the diglycidyl ester of hexahydrophthalic anhydride
