Glass-Film-Glass Hybrid Organic Composites for Forced-Flow Fusion Magnets
The interlaminar shear strength of glass-film-glass organic composites has been tested to check the integrity of the insulating materials used in forced-flow superconducting magnets.
The glass-film-glass (GFG) composites are used as the adhesive insulating material in forced-flow superconducting magnets. The interlaminar shear strength (ILSS) is an important characteristic in maintaining a highly rigid magnet.
Compressive shear tests were performed on GFG materials with different process conditions. The ILSS values of GFG material were found to be low compared to those of conventional composites. The radiation damage of ILSS in GFG material was also examined. It was found that a change of failure mode was brought about by reactor irradiation.
