In order to evaluate the cryogenic compressive properties of G-10CR and SL-
ES30 glass-cloth/epoxy laminates for superconducting magnets in fusion ener
gy systems, compression tests were performed at room temperature (RT), liqu
id nitrogen temperature (77 K) and liquid helium temperature (4 K). The eff
ects of temperature and specimen geometry on the compressive properties are
examined. Photomicrographs of actual failure modes were utilized to verify
the failure mechanisms. (C) 1999 Cryogenic Association of Japan. Published
