Title: Mechanical properties of an insulator for the Japanese LCT coil

Journal Article · · Adv. Cryog. Eng.; (United States)

This study details the investigation of the mechanical and electrical characteristics of several kinds of insulation materials at 4 K in order to select insultors for the Japanese LCT coil. The magnetic and thermal design criteria of the insulator are specified. Procedures for tensile, compressive, bending, bond shear, and thermal contraction tests are given. The materials tested included glass-cloth tape (TE-2513) impregnated with an epoxy resin (KE-5111); epoxy resin (CEMEDIN-1500) sandwiched with cured-eposy glass-cloth tape (SGT-F7036): epoxy glass-cloth laminates FRP plate (VL-E200); and glasscloth sheet (WE-35D100BS) impregnated with polyester resin (PS-518A-20). All materials were found to satisfy the design criteria for compressive strength; others differed. From the test results, the following materials were selected: tape (SGT-F7036) as insulator between turns and pies; voidless FRP (VL-E200) as insulator between the winding and the helium vessel; laminated glass-cloth sheets with polyester (WE-35D100s) were also selected for this category.
