Some insulation for ITER superconducting magnets will be subjected to simultane­ous shear and compressive stresses. The shear/compressive failure envelope of G-11CR, a standardized, but not radiation-resistant, epoxy/fiberglass insulation has been measured at 76 K. A test technique with miniature specimens was employed so insulation could be screened for radiation resistance. Significant differences are reported in the shear strength and shear/compressive failure envelope obtained with this technique and with other shear and shear/compressive measurement techniques.
