Abstract

We have characterized the mechanical properties of a large-grain Y-Ba-Cu-O 46 mm in diameter using the strain gauges. The electromagnetic stress was imposed on the bulk samples by reducing the external field from 7 T to 0 T at 65 K. The sample without resin was broken during the field-decreasing process with the maximum stress reaching 150 MPa. In contrast, the maximum stress was only 40 MPa for the resin-impregnated sample covered with the carbon fiber fabrics. In order to confirm the improvement of mechanical properties through resin impregnation combined with carbon fiber fabric wrapping, we measured trapped fields at lower temperatures. Resin-impregnated Y-Ba-Cu-O bulk 2.4 cm in diameter Sm-Ba-Cu-O bulk 2.4 cm in diameter wrapped with carbon fiber fabric could trap a field of 13.55 T at 36 K and 13.69 T at 47 K, respectively.
